This is a master that can be used to make a paper copy of algebra models. Use two different colored sheet of paper, cut them out and you have a complete set of algebra model tiles. Pieces represent units, x's, y's, xy's, x-squared, and y-squared. With these models students can build a visual understanding for many foundational algebraic concepts.
Also available in my store are templates for Algebra Tiles. The tiles in that set contain only pieces for x's, x-squared, and units.
