Numeracy Ninjas is a free Key Stage 3 numeracy intervention designed to fill gaps in students’ basic mental calculation strategies and also to empower them with the numeracy skills and fluency required to fully access GCSE Maths concepts when they move to Key Stage 4 study.

Furthermore, through growth mindsets and the promotion of regular practice, we want to ensure students’ perception of maths is positive and one in which they take pride and enjoyment.

Numeracy Ninjas is a project driven by the belief that all students can leave school functionally numerate. We aim to put the right resources into the hands of talented maths teachers, completely for free, in order to make this happen.



What’s the problem?

For too long, a levels-based culture focused on ‘rapid and sustained progress’ has only rewarded maths teachers for teaching students content at levels higher than their current test level. Teachers are typically not incentivised to fill gaps in students’ basic lower-level numeracy skills. This is a great frustration to many maths teachers who know regular numeracy strategies practise should be part of all students’ maths lessons.

This systemic problem has to change.

Students who are confident and fluent in the numeracy foundations of maths are better equipped to thrive when they learn the higher-level concepts.

We believe Numeracy Ninjas can play an important role in preventing any gaps students have in their basic numeracy strategies from becoming barriers to their learning.

And, they have gaps… Even the higher-attaining students. Click ‘learn more’ to see some surprising results when we diagnostically tested the numeracy skills of a whole year 7 cohort.

What is Numeracy Ninjas?

Numeracy Ninjas is a whole-school numeracy intervention run in Key Stage 3 maths lessons.

In each lesson students complete a 5 minute skills test which includes: 10 questions on mental numeracy calculation strategies, 10 timestables questions and 10 questions on key topics that must be mastered before studying GCSE Maths.

The tests are marked in class by students who record their Ninja Score out of 30. This corresponds to a particular colour Ninja Belt.

Only a Ninja Score of 30 will earn students the coveted Black Ninja Belt!

Teachers then discuss key mental numeracy strategies related to the questions with the class, before carrying on with their teaching of new learning material.

This little-and-often approach, in combination with a research-informed rota, which systematically plans the revisiting of skills, ensures students’ improved numeracy skills and fluency are retained over time.

Numeracy Ninjas will always be a free product for schools to use and comes complete with the 5 minute skill books; full promotional material to support the delivery of the intervention including posters and certificates; and additional student activities for those students who need a little more support.

Should you like to celebrate students’ success even further, optional Numeracy Ninjas branded merchandise for use as prizes can be purchased from our online shop.
