MathBits: Working with Algebra Tiles
Using tiles to represent variables and constants makes algebra a hands-on proposition that could make solving equations and performing other algebraic functions much clearer. Use this on-line power point
to show how to use tiles in many different ways. First of all, it shows how to make your own tiles and why you might want to make your own in a classroom setting. Work with problems involving factoring, signed numbers, and solving equations. The section on working with polynomials covers adding, subtracting, multiplying, dividing, and factoring.
