This inquiry-based unit teaches students how to solve equations using algebra tiles. It hooks student interest with number tricks that magically undo themselves to give you back your original number, and builds on that concept to teach multi-step equation solving. It assumes no prior knowledge other than operations with positive and negative numbers.

Explain each step in solving a simple equation as following from the equality of numbers asserted at the previous step, starting from the assumption that the original equation has a solution. Construct a viable argument to justify a solution method.

Solve linear equations and inequalities in one variable, including equations with coefficients represented by letters.
