What is Numeracy Ninjas?

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’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!
