Math Learning Wrapup

thingiverse

A customizable OpenSCAD file helps create learning wrap-ups. The file supports addition and multiplication operations. Learning wrap-ups are tools designed for children. This set specifically trains children in addition and multiplication skills. When printed, attach a string to the empty hole. Starting at the top left notch, move the string over to the corresponding solution on the right. Then, return the string along the back to the following notch and repeat until you reach the end. Once finished, turn the wrap-up over. If solutions are correct, the string will match the answer key impressed upon the backside. Example stls are included for the 9* table and the 10+ table. However, any small integer number works (fractions and decimals are not implemented) for both addition and multiplication operations. Each wrap-up can be printed off using about 30g of material, which at a $25/kg cost for PLA amounts to about $7.5 for a set of 10. Comparable products can be found on Amazon for about $7 for a single set or a set of 5 different operations for $45. Amazon offers subtraction, division, and fractions, making it a more comprehensive option.
