What Are Algebra Tiles?

Numerical Models

Algebra Tiles are a very useful numerical model for positive integers, negative integers, and even variables.

Modeling expressions using algebra tiles.

Here are examples of modeling positive integers using algebra tiles.

Modeling positive numbers using algebra tiles.

Here are examples of modeling negative integers using algebra tiles.

Modeling negative numbers using algebra tiles.

You can even model zero by placing a positive tile and a negative tile together. This is called a zero pair. There are multiple ways of modeling zero, so long as equal numbers of red and yellow tiles are used.

Modeling zero using algebra tiles.

Modeling Expressions

Algebra tiles can also be used to model algebraic expressions. To model such expressions, use the tall green tile to model the variable.
