There’s no question about it: we’re at a tipping point for mathematics in the U.S.
Across the U.S., more and more students are reaching middle and high school without the foundational math skills they need to access grade-level learning confidently. Recent NAEP results showed that eighth-grade math achievement still hasn’t recovered from pandemic-era declines, with lower-performing students continuing to fall further behind. High school math scores have also continued to decline, and more seniors than ever before are now performing below the basic level in mathematics.
When foundational skills go unmastered, learning gaps rarely stay isolated; they compound over time, making higher-level mathematics even more difficult to access.
In response, states are introducing new legislation and stronger expectations around intervention, screening, and evidence-based instruction—from Indiana’s HB1634 to Georgia’s Math Matters Act and beyond. In addition to intervention, many also reflect a growing national focus on foundational math skills, numeracy, and procedural fluency as critical building blocks for success in mathematics.
All of this combined has put districts across the country under increasing pressure to identify learning gaps earlier, provide targeted support within MTSS frameworks, and accelerate students toward grade-level proficiency… all without overwhelming already time-strapped educators.
To help you begin to make some headway toward these goals, we’re sharing intervention best practices plus 4 more advanced, research-based strategies to strengthen math intervention in your school or district.
The following strategies can strengthen your math interventions, but none of them matter if students who need support are slipping through the cracks… or if intervention groups are too broad to address the actual root issue.
Here are a few tips to consider:
Before implementing more advanced intervention strategies, make sure you have a strong instructional foundation on which to build. The following best practices help create intervention environments that are structured, accessible, responsive to student needs, and capable of supporting long-term mathematical growth.
What it is: Flexible grouping is an instructional approach where students are grouped and regrouped based on their current learning needs, skill gaps, progress, or instructional goals rather than staying in fixed groups for long periods of time. It may use a mix of small-group, large-group, and individual work to meet student needs.
Why it helps: Flexible grouping allows schools to respond more dynamically to student needs while making intervention more targeted and efficient. Within MTSS frameworks, flexible grouping can also help educators deliver more personalized support without dramatically increasing staffing demands. Groups can shift based on assessment data, classroom performance, observed misconceptions, or specific intervention goals.
Example: Review student work and progress monitoring data. You may notice, for example, that one group of students consistently struggles with regrouping during subtraction, while another has difficulty identifying equivalent fractions. Use that information to create short-term groups focused on those specific skill gaps and deliver targeted mini lessons and scaffolded practice aligned to each group’s needs.
What it is: Deliberate practice combines a few instructional best practices (e.g., challenging practice, goal setting) under one umbrella to result in a more scalable, repeatable system that makes a bigger impact on student learning. It is a structured approach to skill-building where students engage in focused, repeated practice on specific skills. It can be described with the “4 Rs”:
Why it helps: In math interventions, struggling students often need substantially more opportunities to practice a skill before it becomes efficient and transferable. It’s also particularly important that this practice is structured in a way that provides clear opportunities to correct misconceptions and minimize burnout and math anxiety.
This approach also works particularly well within short intervention blocks because it prioritizes consistency and intentionality over lengthy instructional periods.
In practice: Programs like BlueStreak Math make deliberate practice easy with differentiated learning games, immediate feedback on these practice problems, integrated workbooks featuring “Reflect and Learn” prompts, and built-in periods of recovery.
Looking to DIY a deliberate practice model? Prioritize immediate feedback on pencil-to-paper practice and provide opportunities for students to discuss in small groups.
What it is: Gamification is any method of applying “game elements” to the learning process, from actual learning games to contests, leaderboards, and points.
Why it helps: Many students receiving intervention already associate math with frustration, anxiety, or repeated failure. Learning games and other game-based learning strategies like those shared above make intervention feel more fun and less punitive or monotonous. It can help lower that emotional barrier while increasing engagement, persistence, and practice time.
Example: Create a school- or grade-wide contest where students earn points for things like minutes practiced, equations mastered, or other growth metrics. Track these points publicly and ramp up excitement and participation with morning announcements, bulletin boards, and more.

Why it helps: One of the most overlooked barriers in math is cognitive overload. When students must devote significant mental energy to basic computation, they have fewer cognitive resources available for bigger picture or more advanced problem solving and reasoning.
Automaticity–the ability to recall basic math facts quickly and accurately–helps students work more efficiently and confidently. This becomes especially visible in upper elementary and middle school, when students begin tackling more abstract concepts and multi-step tasks.
In practice: Don’t assume students can quickly and accurately recall their math facts as you move on to more advanced strategies and concepts. Even if they once had this ability, it’s important to consistently maintain and strengthen it. Build short periods of fact fluency practice into your students’ daily interventions as a warm-up to prepare them for more cognitively demanding mathematical thinking later in the lesson.
