This circuit is intended as a review for algebra one students after they finish their unit on polynomials but before they start factoring. Addition, subtraction, multiplication, and even a little bit of simple monomial division are all included in this 20-question circuit. There are a few word problems sprinkled in and the answers are all similar so that students must really simplify the entire expression after they perform the operation(s) before they search for their answer. It would be a good review for algebra two students before rational exponents or more advanced factoring.
My colleagues and I check our work very carefully but if you ever get stuck, please don't hesitate to contact me at firstname.lastname@example.org.
