Four Pan Algebra Balance

thingiverse

Introducing an engaging way to understand negative numbers in algebra! The Balance for Negative Integer Fun visualizes negative numbers through a balance model where outer pans represent negatives and inner ones positives, with the tower indicating the equal sign if balanced. This tool is designed for easy 3D printing or laser cutting from a single 1/8" acrylic sheet. It includes a base, towers, tower clips, top beam, mid beams, lower beam, clips, pans, and pointers. Pennies work great as weights, while a laser-cut version is also possible. Have fun learning!
