Number Rumbler – family maths game

Number Rumbler - the charity maths toy

Want to have fun, practise times tables and improve your number sense – all at once?

Back in the spring of 2015 Maths on Toast worked with families in Camden, London to devise a fun maths game that supported understanding of multiplication. In the autumn of 2015 we crowdfunded the result – Number Rumbler – the number sense maths toy. 280 people backed the STEM game, whether by buying advance copies for themselves or making donations.

The maths game was a Finalist in the 2016 Science Toy Award. It is also recommended within National Numeracy’s Family Maths Toolkit, and (as well as a cluster of Amazon reviews) there’s a Kids in Museums review of Number Rumbler here.

Number Rumbler’s now available to buy – online, and in some retailers. It costs just £7.

Number Rumbler: the game where you can have fun, practise times tables and improve your number sense – all at once!

 

Introducing… Number Rumbler!

Number Rumbler is a brain-fizzing, fun maths card game for families – anyone from 6 to adult can join in. When you play it you’ll be having fun, practising your times tables, and developing number sense – all at the same time.

Number Rumbler was developed by family maths charity Maths on Toast. We’re really proud of Number Rumbler and we want to get more people playing it!

How does Number Rumbler help with number sense?

Number sense is what it sounds like: a sense for numbers. Learning multiplication tables is all about number facts: 2 x 5 is 10, for example. Number sense is deeper, more fun and more valuable. It’s about understanding how numbers relate to each other more broadly.

The family maths game

Number Rumbler consists of a pack of cards with numbers written – and drawn – in different ways. For example, 12 could be 4+4+4 or 3×4 or drawn out as twelve dots. By playing with the cards, you’ll get a better sense of how the numbers relate to one another – and because of that understanding, you’ll be more flexible with numbers and more fluent when you’re calculating and estimating.

How to Play

You can play noisy or quiet games with Number Rumbler – it’s up to you. A great way to start is simply to sort the cards into families – all the 12s, all the 10s, and so on. You might also want to take out some of the cards if you’re playing with younger children – the blue division cards, and the green cards with words on.

What people say

“[Number Rumbler] was really fun” – child’s comment

“I enjoyed it” – child’s comment

“Where can I buy this maths game?” – parent’s comment

“This is a fun maths game for all the family which can be used in a number of different ways … The cards show quantities as calculations as well as dot arrays and this helps children to see relationships between the different representations and thus improve their number sense. A very simple but effective idea!” Margaret Haseler, Primary Lead Consultant, National Numeracy

“At last a maths number game for children to play with friends and family that really supports them to develop their number sense – and practice some important number facts along the way.. There’s no better way to learn and practice those times tables!” Dr Alison Clark-Wilson, Research Fellow, UCL Institute of Education, and Trustee, Maths on Toast

“Making maths fun for children……..that certainly happened at The Winch during this project! It is a fantastic idea and has opened the door to children who, not only like maths, but also those who find it challenging. Maths on Toast has been a great organisation to partner with, if you’re interested in making maths fun for children, please support their crowdfunding campaign!” Kim Mabbutt, Play Development Officer, The Winch

“In these troubled times what the world needs is more numbers. And it
seems to me that multiplication is the best way to get them.” Dr Paul Wilmott, Financial Mathematician, Lecturer, and Founding Trustee, Maths on Toast

Some More Backstory

We developed this STEM maths game by working with real children and parents in the London Borough of Camden. Thanks to their input, this game is much better than it would have been otherwise. So thanks are due to the team at The Winch and at Pancras Square Library – and also to John Lyon’s Charity for funding the early development of the game.
