These number blocks from 1 to 10 can help children to understand easier the basic arithmetic operations. You can compare the sizes of the block, e.g. block 2 and block 8 combined have equal length as block 10. This visual and haptic help makes adding and subtracting easier.

When you print each block multiple times, for example 10-20 blocks of each size, this system can be even more flexible. You can create tasks according to your childs skill and school grade.

The blocks have a size of 10mm per number. That makes it easy to use rulers for calculation. The board on second print plate can be used for calculations up to 100.

Printing:

I put all blocks on one plate, but you may arrange them according to your need. It is best to use a different color for each size, so maybe you put all blocks of one size on a plate.
