visual algebra

There are two sets of algebraic identities usually taught at the school level - (i) the quadratic ones and (ii) the cubic ones. Both can be modeled in a low-cost way. Nets of solids can be used for the cubic identities. Layouts of both are included along with links to uses.

Algebra tiles are a powerful manipulatives to understand algebraic expressions in single variable up to degree 2. They prevent some misconceptions and can be used all the way till middle-term factorization. They can be easily made from cardboard boxes.
