4. Xtramath
Targeted Skills: Computational Fluency
Level: Tier 1 & Tier 2
A quick and easy intervention for math fact fluency. The site includes great data and offers support for struggling learners.
Students work to answer basic computations and build fluency and accuracy quickly. If it takes a student too long to answer, the program gives them a visual cue with the answer, but they still have to enter it. Over time the program rotates through the problems the student has yet to master, working them toward fluency.
Over time the program rotates through the problems the student has yet to master, working them toward fluency.
As with any site, it has some pros and cons. One pro is that it is great for accurate students but not yet fluent with their math facts. You might use it in conjunction with these great math fact games. That said, it isn’t great for kids still building a conceptual understanding of computation.
5. Mathematics Assessment Project (MAP)
Targeted Skills: Middle & High School Math Skills

So many websites cover the basics and don’t hit on those higher-level math concepts. This website is great for Tier 1 and Tier 2 intervention for more advanced math classes.
The site has lesson plans and printable materials that make it easy to implement, and there are many hands-on performance tasks.
One thing I liked about the site is that performance tasks are sorted from “novice” to “expert,” meaning you can do some differentiating in your classroom to support all learners best. While working with your struggling students to build conceptual knowledge using a novice task, you can challenge your advanced learners.
The tasks are also all real-life scenarios, which makes them engaging and purposeful.
6. Freckle
Targeted Skills: Standards-based math skills
Level: Tier 1
This site offers a free teacher account and is great for those students who need a Tier 1 reteach and extra guided practice and support. The program begins with a diagnostic assessment, which helps you identify gaps and targets for support.
With built-in assessment and differentiation, the program monitors how students progress. It also gives modeling and visuals for problem-solving. This is great for students struggling with a specific concept or below grade-level standards. Plus, it works on tablets!
There are also K-2-friendly lessons and resources on this site, which isn’t always the case with math intervention sites.
While it isn’t for Tier 2 or Tier 3 interventions, one pro of the site is that it offers a computer-adaptive format and robust reporting that can help you determine when extra exposure and reteaching aren’t enough. This can help you come to SST meetings better prepared to advocate for learners.

16. Formative Loop
Targeted Skills: Computational Fluency
Level: Tier 1 & Tier 2
Okay, so I will start with a caveat on this one. The site is paid, but it offers a free trial…and one of the longest I’ve seen. You can access and use Formative Loop for up to a year.
The idea of this one is that students are given personalized practice, and that practice informs the problems the students receive the next day. Basically, it’s the same concept as repeated reading, but for math.
While not ideal for students lacking conceptual understanding, it is great for building fluency. A major pro is that it takes five minutes of your instructional day. That’s it!
17. Intervention Central
Targeted Skills: Varies
Level: Tier 2 & Tier 3
Intervention Central is an amazing resource focused on providing teachers with research-based intervention strategies.
Unlike some of the other sites I am listing, this one will take you a bit more time to read and process, but it outlines all the steps for some strong, research-based intervention strategies, along with citations so you can read the original study (if that is your thing).
PROS: Research-based interventions with step-by-step directions & references
CONS: Not the prettiest site; not print & use
