To use algebra tiles you have to have a variety of tiles ranging from small to large. Usually they have defined units of variables, and integers. For example ‘1, x, and x^2’ x being the variable. Now if you are given an expression you want to model or show it using these tiles. You get the quantity of the number and put one tile for each specified number, or coefficient. A strategy to remember when using algebra tiles is zero pairs. This is a way of simplifying equations to make them easier to understand. If there is a negative number and a positive, and they both represent the same number, or there is adding a unit and the same unit is being subtracted you can take those out of the equation (make sure it is 1:1) and those that are left are the simplified question.
