# Math Intervention

*By Margy Hillman*

## Introduction

Concern over K-12 mathematics education has existed for decades. In fact, the various disagreements have been titled the “math wars.” Key questions include: Which is the best content for each grade? What is the most effective pedagogy? Should students all receive the same math content?

Recent headlines warn that national math scores have never been worse. They describe an alarming 5-point drop in 4th-grade achievement. However, US fourth-grade scores have hovered between 235 and 242 from 2003 to 2022. And the scores have increased and decreased from year to year. For example, the average score in 2019 was 241 and in 2022 it was 236. The 5-point drop was equally shared across most student groups. The proficiency score (student at grade level) has never reached the minimum of 249.

The complex issue of how best to intervene and bring students to an average of grade-level proficiency is even more critical when we look at the dismal average scores of students of color, students from low-income families, and students with disabilities. At the very core of this issue is realizing the promise of public education for all students.

Our democracy can’t succeed without a high-quality, equitable public education system that helps students build the knowledge and skills they need for their future, and provides a level playing field for everyone. Public schools continue to be weakened by the historic racism and inequity that define our current system. If our education system prioritizes some students over others, it leaves a generation of young people without the opportunity to succeed.

(Partnership for the Future of Learning, 2022).

Effective research-based intervention programs that remove math gaps and accelerate grade-level proficiency provide solutions that every district and school can successfully adopt and implement so that all students experience optimal success in math learning.

## Key Terms in Math Intervention

**What is math intervention?**

Math intervention provides targeted support to students who are struggling with mathematics concepts and skills. The specific components of a math intervention program can vary depending on the grade level, the needs of the students, and the goals of the program. It’s important to note that the specific design and components of a math intervention program can vary widely based on the educational institution, the grade level of the students, and the resources available. The goal of these programs is to help struggling students fill gaps and reach grade-level proficiency with a solid foundation in mathematics.

**What is dyscalculia?**

Many teachers, parents, and children are unfamiliar with the term dyscalculia, which is often mistakenly called “math dyslexia.” Dyscalculia describes a unique neural condition that affects learning skills related to math or arithmetic. According to research, “The difficulties are not due to a disorder of intellectual development, sensory impairment, mental or neurological disorders, or inadequate instruction (WHO, 2018)” (McCaskey et al., 2020).

Educators commonly call dyscalculia a learning disability, although some researchers believe it is more properly described as a learning difference. The condition was identified in 1919 by Salomon Henschen, a Swedish neurologist, who discovered it during his studies of aphasia and visual pathways of the brain. However, the condition stayed primarily in the province of neurology until the 21st century, when it moved into mathematics education research. It is estimated that dyscalculia affects between 5% and 7% of students and occurs about equally in males and females.

Difficulties common to learners with dyscalculia include:

- Connecting numbers and words that represent numbers
- Recognizing patterns
- Putting things in order
- Learning math facts
- Estimating such things as height, width, or depth
- Adding and subtracting
- Keeping track when counting
- Moving from finger counting to mental counting
- Making sense of charts and graphs

Research shows that the best way to support students with dyscalculia is to present interventions that focus on math learning gaps and that use “multisensory teaching methods, building a child’s confidence, high teacher expectations, and parental support” (PenCRU, 2018).

Although we are still in the early stages of understanding how to support students with dyscalculia, we do know some of the strategies that work: “explicit, repetitive instruction, more time to understand how symbols represent quantity, playful activities to avoid math anxiety, and suggestions for finger counting in more sophisticated ways” (ASCD, 2020). Most of these strategies will benefit all students; they can be used in MTSS and RTI environments. Fortunately for teachers of students who may have dyscalculia, Let’s Go Learn’s system for math education matches the support that ASCD recommends for these students.

Let’s Go Learn’s Dyslexia Screener, DORA DS, makes it easy for teachers to assess an entire class quickly to identify students who may need reading intervention. Our screener takes most students only 10-15 minutes to complete, and it is automatically scored with reports ready in real time. Students’ dexterity with their devices is measured first to ensure the validity of results.

**How many types of math assessment are there?**

Assessing a student’s math gaps is essential for providing targeted support and intervention. There are several effective ways to assess a student’s math gaps:

- Standardized Tests: Standardized math assessments, such as state-standardized tests or nationally normed tests, can provide a broad overview of a student’s math skills. These tests often cover a range of math topics and can help identify areas where a student is performing below grade level.
- Benchmark Assessments: Benchmark assessments occur at regular intervals to measure mathematics skills during the school year. The first benchmark of the year sets a baseline, and the remaining benchmark assessments measure progress and student achievement.
- Diagnostic Assessments: Diagnostic assessments are designed to pinpoint specific areas of weakness. They are often administered by teachers and can include both written assessments and one-on-one interviews with the student to identify gaps in knowledge and skills.
- Curriculum-based Assessments: Teachers can assess a student’s understanding of specific math concepts by using assessments aligned with the curriculum being taught. These assessments can be administered periodically to track progress.
- Formative Assessment: Formative assessment involves ongoing informal assessments conducted during instruction. Techniques like quizzes, exit tickets, and classroom observations can help identify immediate misunderstandings or gaps as they arise.
- Review of Past Work: Carefully reviewing a student’s previous math assignments, tests, and homework can provide insights into recurring areas of difficulty.
- One-on-One Interviews: Teachers can engage in one-on-one discussions with students to assess their math understanding. This approach allows students to explain their thought processes and reveal areas of confusion.
- Math Portfolios: Collecting a portfolio of a student’s math work over time can provide a holistic view of the student’s math skills, including strengths and weaknesses.
- Peer or Self-Assessment: Sometimes students can assess their own understanding or evaluate their peers’ work. Peer or self-assessment activities can reveal gaps in comprehension when students struggle to explain concepts or provide accurate feedback.
- Math Software and Online Tools: There are various educational software programs and online tools that offer adaptive assessments. These tools can adapt to a student’s level and provide targeted questions to identify gaps.
- Observation and Classroom Performance: Teachers can observe students during math class to assess their participation, engagement, and ability to apply math concepts. Their observations can provide valuable insights into gaps in understanding.
- Parent Input: Parents or guardians can provide valuable information about their child’s math struggles and areas of concern. Collaborating with parents can help in identifying gaps and developing a plan for support.
- Rubrics and Checklists: Teachers can use rubrics or checklists to assess specific math skills or concepts. These tools provide clear criteria for assessment and can help identify gaps in a structured way.

Combining multiple assessment methods can provide a more comprehensive understanding of a student’s math gaps. Once gaps are identified, educators can develop targeted interventions and strategies to help the student catch up and build a solid foundation in mathematics. It’s important to note that ongoing assessment and progress monitoring are key components of effective math instruction and intervention.

## Common Core State Math Standards (CCSS), 2010

The Common Core State Standards (CCSS) for Mathematics, often referred to as the Common Core Math Standards, are a set of K-12 educational standards for mathematics in the United States. Developed by a consortium of states, these standards were designed to provide a clear and consistent framework for what students should learn in mathematics at each grade level, ensuring that they are well prepared for college and career. Here is a brief description of the key features and components of the Common Core Math Standards:

- Grade-level Expectations: The Common Core Math Standards specify what students are expected to learn in mathematics at each grade level, from Kindergarten through grade 12. The standards are organized into grade clusters: K-2, 3-5, 6-8, and high school.
- Focus on Fewer Topics: One of the distinctive features of the Common Core Math Standards is the focus on a smaller number of key topics or concepts at each grade level. The intention is to promote a deeper understanding and mastery of fundamental mathematical principles.
- Coherence and Progression: The standards are designed to be coherent and build upon each other as students progress through the grades. They aim to ensure that students develop a strong foundation in mathematics and are prepared for more advanced concepts.
- Mathematical Practices: In addition to content standards, the Common Core Math Standards include a set of eight mathematical practices that describe the behaviors and habits of mind that proficient math students exhibit. These practices emphasize problem solving, reasoning, and mathematical communication.
- Real-world Application: The standards emphasize the importance of connecting mathematical concepts to real-world situations, modeling, and problem solving. This approach helps students see the practical applications of mathematics in various fields and careers.
- Rigorous and Conceptual Understanding: The Common Core Math Standards stress the importance of students not only knowing how to perform mathematical procedures but also understanding why these procedures work. This promotes a deeper conceptual understanding of mathematics.
- Assessment Alignment: The standards are often accompanied by aligned assessments, including both formative assessments (to gauge student understanding during instruction) and summative assessments (to measure overall proficiency). These assessments are designed to reflect the standards’ focus on conceptual understanding and problem solving.
- Flexibility for Educators: While the standards provide a clear outline of what should be taught at each grade level, they also allow flexibility for educators to design instructional approaches and materials that best meet the needs of their students.

It’s important to note that over time, each state has customized the original standards, although the key elements have changed very little.

## State Customization of the CCSS

State-customized versions of CCSS are often referred to as “state-specific adaptations” or “state-added standards.” Here’s how states have typically customized the CCSS:

- Additional Standards: Some states added standards that were not originally included in the CCSS. These additional standards might cover specific content areas, skills, or topics that the state deemed important. For example, a state might add standards related to state history or local geography.
- Modifications to Language: States have sometimes modified the language of the CCSS to make them more accessible or to clarify certain concepts. These modifications could include rewording or simplifying standards for different grade levels.
- Reordering or Combining Standards: States might rearrange the order of standards or combine multiple standards into a single standard. This can be done to better align with the state’s curriculum or instructional approach.
- Grade-level Adjustments: In some cases, states have adjusted the grade level at which certain standards are introduced. For example, a state might decide to introduce a specific mathematical concept in a different grade than what is outlined in the original CCSS.
- Deletions: States may choose to remove specific standards or topics from the CCSS that they do not consider essential or relevant to their educational goals, which allows for a more streamlined curriculum.
- Additional Resources: States often provide additional guidance, resources, or sample materials to help educators implement the standards effectively. These resources may include curriculum frameworks, model lessons, and professional development materials.
- Assessment Alignment: States that have their own standardized assessments may align these assessments with their customized versions of the CCSS. This ensures that the tests reflect the specific content and skills emphasized in the state’s standards.

It is important to note that not all states made significant modifications to the CCSS. Some states adopted the standards with minimal changes, while others made more extensive alterations to better suit their educational goals and local contexts. The degree of customization varied from state to state.

A number of states now require math support for struggling students. These include the following states:

- Alabama. 2022. SB 171
- Arkansas. 2023. SB 294
- Colorado. 2023. HB23-1231
- Florida. 2023. HB 7039
- Louisiana. 2023. SB 163
- Virginia. 2022. HB 938
- West Virginia. 2023. HB 3035

**States That Have Not Adopted or Adapted CCSS**

There are some states that never approved the original CCSS. These states either chose not to adopt the CCSS at all or had previously adopted them but later repealed or replaced them with state-specific standards. Some of the states with non-Common Core standards include:

- Texas: Texas was one of the earliest states to reject the Common Core standards. Instead, they have their own set of standards called the Texas Essential Knowledge and Skills (TEKS) for various subjects, including mathematics and English language arts.
- Alaska: Alaska chose not to adopt the Common Core standards and developed its own Alaska Content and Performance Standards for English Language Arts and Mathematics.
- Oklahoma: Oklahoma initially adopted the CCSS but later repealed them and replaced them with the Oklahoma Academic Standards for English Language Arts and Mathematics.
- Nebraska: Nebraska never formally adopted the Common Core standards. Instead, they have their own state standards for education.
- Virginia: Virginia originally adopted the CCSS but later made modifications to create the Virginia Standards of Learning (SOL) in English, mathematics, science, and history.
- Indiana: Indiana initially adopted the Common Core standards but later withdrew from the initiative and replaced the standards with their own Indiana Academic Standards.
- South Carolina: South Carolina initially adopted the CCSS but later withdrew from the standards and replaced them with the South Carolina College and Career-Ready Standards.
- Missouri: Missouri initially adopted the Common Core Standards but later reviewed and revised them to create the Missouri Learning Standards for English Language Arts and Mathematics.

It’s important to note that education policies can change, and states may revisit their standards over time. Therefore, the status of standards in each state will continue to evolve.

## Math Intervention Programs & Equity and Inclusion

It’s important to note that math intervention programs are designed to address the specific needs of students, so the selection of topics and the depth of coverage can vary. These programs typically begin by assessing students’ math skills to identify gaps and then provide targeted instruction and practice in areas where students are struggling the most. As students progress, the intervention may extend to more advanced topics based on students’ readiness and needs.

## Popular Evidence-based Intervention Solutions

Effective math intervention strategies have been the subject of extensive research in the field of education. Several research studies have investigated approaches and methods to support students who are struggling with mathematics. Some influential studies and research-based strategies that have garnered attention for their effectiveness in math intervention are described below.

**RTI/MTSS Math Intervention**

RTI (Response to Intervention) and MTSS (Multi-Tiered System of Supports) are both educational frameworks that provide structured approaches to supporting students who may be struggling with academic skills, including math. While there is overlap between the two, there are also key differences in their focus and scope.

Here’s a breakdown of the main differences between RTI and MTSS math intervention:

### Focus

- RTI (Response to Intervention): RTI primarily focuses on identifying and providing interventions for students who are struggling academically. It is often associated with academic interventions to address specific learning difficulties, including those related to math. RTI is more narrowly focused on academic response and progress.
- MTSS (Multi-Tiered System of Supports): MTSS is a broader framework that encompasses academic, behavioral, and social-emotional supports for all students. While it includes academic interventions like RTI, it also addresses a wide range of student needs, including behavior, attendance, and social-emotional well-being.

### Tiers

- RTI: RTI typically consists of three tiers. Tier 1 is universal instruction (core curriculum) for all students, Tier 2 is targeted intervention for students at risk, and Tier 3 is intensive intervention for students with significant learning difficulties.
- MTSS: MTSS incorporates multiple tiers, but it can include more than three. While academic interventions are an essential component, additional tiers are included for behavior, social-emotional learning, and other areas of support.

### Comprehensive Approach

- RTI: RTI is primarily focused on academic interventions, and its primary goal is to improve academic outcomes for students. It may not address other areas of student well-being or support services.
- MTSS: MTSS takes a more holistic approach, recognizing that students’ needs go beyond academics. It addresses the whole child and provides a framework for schools to coordinate and integrate various support services.

### Data Utilization

- RTI: RTI relies heavily on academic data, such as assessments and progress monitoring, to identify struggling students and guide intervention decisions. It is primarily data driven and focuses on academic response to interventions.
- MTSS: While MTSS uses academic data, it also incorporates non-academic data, such as behavioral and social-emotional data, to provide a more comprehensive understanding of a student’s needs. This broader range of data informs decisions about the appropriate tier of support.

### Collaborative Team Approach

- RTI: RTI often involves educators and specialists working together to design and implement academic interventions. It may not always include a full team approach that addresses all aspects of a student’s well-being.
- MTSS: MTSS emphasizes a collaborative team approach that may include educators, counselors, behavioral specialists, and other professionals to address different student needs.

In summary, while both RTI and MTSS involve tiered interventions and data-driven decision making, RTI is more focused on academic responses to intervention, while MTSS is a more comprehensive framework that addresses a broader range of student needs, including academic, behavioral, social-emotional, and wellness supports. MTSS is designed to promote a holistic approach to supporting the well-being and success of all students.

For students with disabilities or students at any MTSS/RTI Tier, LGL’s progress-monitoring process consists of five steps: 1) LGL diagnostics analyze and identify each student’s learning gaps and present levels (PLAAFP); 2) IEP teams develop individualized education programs (IEPs) using LGL narratives, diagnostic data, and alignments to standards; 3) The LGL system assigns specially designed instruction (SDI) for students with disabilities and places them in lessons at their zone of proximal development. Teachers can always self-select lesson assignments; 4) LGL provides progress monitoring with pre-built skills and concepts quizzes and tests. Teachers queue assessments, and data automatically overlay onto the original dataset; 5) LGL math curriculum also provides ongoing progress monitoring, tracking student academic performance from the initial evaluation. Teachers are not required to collect data, so they can concentrate on interpreting and implementing mathematics instruction.

**Math Recovery**

Mathematics Recovery is an evidence-based intervention program designed to provide targeted support to students who struggle with mathematics. This program is primarily aimed at early elementary school students but can be adapted for older students as well. Math Recovery was developed by Dr. Robert J. Wright and his colleagues and is based on research in mathematics education and child development. Here are some key features and components of the Math Recovery Program:

- Individualized Assessment: The program begins with a thorough, individualized assessment of each student’s mathematical understanding. Specially trained Math Recovery specialists conduct these assessments to identify specific gaps in a student’s mathematical knowledge and skills.
- One-on-one Instruction: Math Recovery sessions typically involve one-on-one instruction or instruction in very small groups. This personalized approach allows the Math Recovery specialist to tailor the intervention to the student’s unique needs.
- Concrete-Pictorial-Abstract Approach: Math Recovery emphasizes the use of concrete materials, pictorial representations, and abstract symbols to help students understand mathematical concepts. This approach aligns with research on how young children develop mathematical understanding.
- Focus on Number Sense: Number sense, which includes an intuitive understanding of numbers, quantities, and relationships, is a central focus of Math Recovery. Students work on building a strong foundation in number sense to support their overall mathematical development.

## NCII Intervention Strategies

The National Center on Intensive Intervention (NCII) provides resources and guidance on evidence-based practices and intervention strategies in education, including mathematics. NCII focuses on helping educators implement interventions effectively to support students with diverse learning needs, including those who are struggling in mathematics. While NCII does not endorse specific intervention programs, it does promote the use of evidence-based practices. Here are some key principles and strategies often associated with NCII’s approach to math intervention:

- Data-driven Decision Making: NCII emphasizes the importance of collecting and analyzing data to inform intervention decisions. This process includes using data to identify students needing support, monitor their progress, and adjust instruction as necessary.
- Screening and Assessment: NCII recommends using screening tools and assessments to identify students who may be at risk of experiencing math difficulties. These assessments help educators pinpoint specific areas of need and determine appropriate interventions.
- Tiered Intervention Model: NCII promotes the use of a multi-tiered system of supports (MTSS) or response-to-intervention (RTI) framework, which includes three tiers of support. Tier 1 provides high-quality, universal instruction for all students, while Tiers 2 and 3 offer increasingly intensive interventions for students who require additional support.
- Evidence-based Instructional Practices: NCII encourages the use of evidence-based instructional practices in math interventions. These practices are grounded in research and have been shown to be effective in improving student outcomes. Examples include explicit instruction, visual representations, and systematic instruction.
- Progress Monitoring: Educators are encouraged to use ongoing progress monitoring to assess whether interventions are working and to make data-driven decisions about whether to adjust or intensify instruction. Progress-monitoring tools and assessments are typically used.
- Individualized Instruction: NCII recognizes that students have unique needs, and interventions should be tailored to each student’s specific difficulties and strengths. Individualized instruction ensures that interventions are matched to the student’s level of readiness and need.
- Fidelity of Implementation: To ensure that interventions are delivered as intended, NCII emphasizes the importance of fidelity of implementation. This means that educators should follow the intervention program with fidelity, adhering to the recommended procedures and strategies.
- Collaboration: Collaborative teamwork among educators, specialists, and support staff is essential in implementing effective math interventions. Collaboration facilitates data sharing, decision making, and coordination of support services.
- Professional Development: NCII supports ongoing professional development for educators to ensure that they have the knowledge and skills necessary to implement evidence-based math interventions effectively.
- Family Engagement: Involving parents and caregivers in the intervention process is considered crucial. Educators should communicate with families, share progress data, and provide resources for supporting the child’s math development at home.
- Cultural Responsiveness: NCII acknowledges the importance of culturally responsive practices in intervention. Educators should consider students’ cultural backgrounds and experiences when designing and implementing interventions.

It’s important to note that while NCII provides resources and guidance on math interventions, the specific intervention program or strategy may vary by school, district, or individual student needs. Educators often select or design interventions based on the best available evidence and the unique needs of their students. The overarching goal is to ensure that all students receive the support they need to succeed in mathematics.

LGL Math Edge provides a research-based, data-driven, systematic math curriculum that increases student math abilities across any mathematics initiative. Lessons are highly effective and diagnostically driven. They close gaps, boost students’ math skills and concepts, and can be used as supplemental SDI for students with IEPs. Teachers can use the lessons at math centers, for pull-out interventions, or for general classroom mathematics instruction. For schools using MTSS or RTI, scaffolded lessons are automatically generated for every tier.

## Math Anxiety & Need for Math Intervention

Math anxiety refers to a feeling of apprehension or fear when it comes to mathematics. This anxiety can have significant consequences for students, both in terms of their academic performance and overall well-being. Here are some of the potential consequences of math anxiety:

- Poor Academic Performance: Math anxiety can lead to a decrease in math grades and overall academic performance. Students who are anxious about math often struggle to concentrate and perform poorly on tests and assignments.
- Avoidance of Math: Individuals with math anxiety may actively avoid math-related tasks and courses, which can limit their educational and career opportunities. This avoidant behavior can perpetuate the problem, as they miss out on opportunities to improve their math skills.
- Negative Self-Perception: Math anxiety can erode an individual’s self-confidence and self-esteem. When students consistently struggle with math, they may start to doubt their abilities in other areas as well, leading to a negative self-image.
- Reduced Career Options: Math skills are essential in a wide range of professions, including STEM fields, finance, and many others. Math anxiety can limit career choices and opportunities for individuals who are otherwise capable but are held back by their fear of math.
- Emotional Distress: Math anxiety can lead to emotional distress, including feelings of frustration, helplessness, and even depression. The constant worry about math-related tasks can take a toll on a person’s mental and emotional health.
- Physical Symptoms: Some individuals may experience physical symptoms of anxiety, such as increased heart rate, sweating, and nausea when faced with math-related tasks or tests.
- Decreased Problem-solving Skills: Math anxiety can interfere with a person’s ability to think logically and solve problems, not just in math but also in everyday situations that require critical thinking and analytical skills.
- Limited Financial Literacy: Math anxiety can hinder a person’s ability to manage finances effectively, as many financial tasks involve basic mathematical concepts. This can lead to financial difficulties in the long run.
