WHAT IS NUMERACY NINJAS?

Close Numeracy Gaps—Fast

GAMIFIED SCORING ▸ MINIMAL PREP ▸ EVIDENCE-BACKED IMPACT

The Cognitive Science Behind Numeracy Ninjas

Our approach isn’t guesswork—it’s grounded in decades of robust cognitive research:

Spaced & Interleaved Practice

Rather than massed “drill and kill,” we distribute practice over time and mix different skills in each session. This spacing and interleaving builds stronger, more durable memory traces, so students retain concepts far longer and transfer them flexibly to new problems.

Low‑Stakes Retrieval

Frequent, short quizzes encourage active recall without the pressure of high‑stakes tests. Every prompt is a safe opportunity to pull information from memory—strengthening neural pathways and reducing the “forgetting curve.”

Immediate Feedback Loops

Instant scoring and belt promotions close the learning loop in real time. Students immediately see where they excel and where they need more work, which both accelerates correction of misconceptions and fuels sustained motivation.

Targeted Skill Clusters & Progressive Interleaving

We begin by concentrating on small groups of related skills across several consecutive sessions. Once mastery is established, we gradually weave these skills together—interleaving them with new topics. This scaffolded progression fosters both deep understanding and flexible application.

Combined, these evidence‑based strategies turbocharge mental‑math fluency. Numeracy Ninjas doesn’t just help students practice harder—it helps them learn smarter.

Don’t Just Take Our Word For It

Numeracy Ninjas has been a huge success. Thanks for all your hard work.

Numeracy Ninjas takes place in all of our KS3 classes weekly. Every class completes 1 session of Ninjas and 1 follow up session weekly. The follow up session allows us to build upon key skills where they need more support. Monthly we celebrate the top 10 in y7, 8 & 9 who have shown consistency or improvement. Students love watching their progress through the belts and challenging each other to improve weekly!! So much love for Numeracy Ninjas at our school.

I have been using Numeracy Ninjas daily in the classroom with great success.

I’m absolutely obsessed with the Numeracy Ninjas resources available! A new 23/24 version is out… I can’t wait to use these in the classroom!

I’ve subscribed for 5 weeks for free… After using these a few times in the lessons it’s been an absolute hit with the children. They’re so motivated to pass the next belt colour as well! I’m so proud to say I am using these resources in September. They also provide assessments which can be used for intervention purposes as well!

@numeracyninjas, you’ve won me over, wish I knew about you before!

Ninjas has even engaged students with Dyscalculia…it’s phenomenal! It’s repetition which is what students with Dyscalculia need. Sometimes we need to just trust a mathematical principle rather than force a reason, and for this particular student, Ninja has been amazing!

By the end of 2023 school year (we have one week to go), I regularly had 5+ black belts, 5-10+ brown belts, and the majority, despite learning difficulties, all above 50%! I love everything about Ninja…and the disappointment when a Maths lesson didn’t start with Ninja said it all!
