## 3D model description

####Jigsaw Number and Operator Pieces

##### "God made the integers ; all the rest is the work of Man." ( Leopold Kronecker).

Children like jigsaw puzzles, especially when the big picture emerges! Numbers work much the same way. When arranged in meaningful patterns, number sequences are fun to play with. For example, what is the sum of all integers between 0 and 9? So I decided to design some jigsaw numbers pieces and some corresponding operators. Please print whatever is appropriate for your audience.

Each piece is 25mm x 25mm x 5mm. Multiple copies can be printed for open explorations. Please do teach children how to use parentheses or other means to avoid run-on number sentences such as 3+2=5+4=9, which, as a whole, does not make sense. At least, children should know that such run-on use of “=” should be read piece by piece in a number game and is unacceptable in mathematics.
####Notes
1. To highlight the numbers, please use a permanent marker to trace them after printing. Or, if you like, you could change the filament toward the end (say, 5%) and print the numbers in a different color.

1. Twist a little bit to separate the pieces after printing.

2. Increase the layer thickness for tighter connection; decrease the layer thickness for loose connection.
