Bracket Expansion – Algebraic Montessori-Inspired Learning Tool

Make learning algebra hands-on and engaging with this Montessori-inspired bracket expansion puzzle! 

This physical representation of algebra was designed for upper elementary students (grades 4-6). The purpose is to use physical shapes to represent the bracket expansion formula:

(A+B) × (C+D) =

(A×C) + (A×D) + (B×C) + (B×D)

How It Works:
The color-coded blocks fit snugly into the base but can be removed and rearranged, allowing students to physically interact with each term of the equation.

The base has 
 
Printer Used: Bambulab X1 Carbon
Material: PLA filament
Settings: 15% infill, 3 walls
Color Printing: Recommended for better differentiation and text readability, but a single-color print should work well!
