Sumblox are a set of wooden blocks which are shaped like the digits 1-10. What’s really cool about them is that they increase in size relative to the number represented.

These blocks are a maths teaching tool with a difference.
SumBlox are a wooden block set of numbers 1-10.

These amazingly smooth and tactile wooden block numbers each range in size according to their number they represents. (1 being the smallest and 10 the biggest.

The most mind blowing mathematical bit though is that when the blocks are stacked, they represent the equivalent number. For example, when the 2 and 3 blocks are stacked, they are the same height as a 5 block standing up !

This is a large set (Number 10 is 15cm)
