Algebra tiles are physical manipulatives used to help students visualize and understand algebraic equations. They are typically made of plastic and come in two shapes: squares and bars. The squares represent constants, such as numbers, and the bars represent variables, such as x and y.
When representing linear terms, the algebra tiles are arranged in pairs. The squares represent the constant term, and the bars represent the variable term. For example, if the linear term is 3x, the algebra tiles would be arranged as one square and one bar.
Zero pairs are represented by two squares, one for each side of the equation. This is because when two terms are equal, they cancel each other out and the result is zero. For example, if the equation is 3x + 3x = 0, the algebra tiles would be arranged as two squares.
Explain how algebra tiles represent lien terms and zero pairs.
