Equivalent Expressions - Distributive Property (1)

This interactive Java learning tool, constructed using GeoGebra, allows a teacher to demonstrate and students to explore the distributive property of multiplication over addition. Students see the relationship between two different algebraic expressions: a(l+w) and a(l) + w with side-by-side diagrams that allow for comparison. The models shown can be determined by checking boxes and the sliders change the values of each variable.
