Binary Numbers, Base Two System, Place Values

A scaffold for children to learn about binary numbers or numbers in the base two number system (0 to 11111, corresponding to 0 to 31 in the base ten system). The stand has five positions and is about 120mm long. It takes five number pieces to play the binary game (ranging 0 from 31).
The number piece has "1" on the front and "0" on the back. I have designed the numbers for easy sliding and 3D printing. Have fun!
