Proportional Number Blocks + Storage Case

Blocks of the numbers 1-10 in sizes proportional to one another. 

Useful for practicing number recognition/recall, counting, numerical values, addition, as well as the commutative property of addition.  

When stacked, the height of the stacked blocks will be the same height as any other stack of blocks with the same sum. 

For example, if blocks 6, 5, and 4 are stacked, the stack will be the same height as a stack of blocks 6 and 9, as seen in the model photos (both stacks have a sum of 15; 6+5+4=15; 6+9=15).

Scaling should not affect the proportional nature of the models as long as they are all scaled the same amount. 

Edit Jan 14, 2025
Added storage boxes, one with mated features for stacking, and one without. 
Replaced the file for Number Block 2 - there were some body errors in the original. 
Added Step files for all.
