I wrote this circuit for my 8th, 9th, and 10th grade algebra one students so they could get better at the CCSS "seeing structure in an equation" standard. Students will be highly engaged as they work through the 16 linear and quadratic equations that get progressively more difficult. Students begin on cell #1 and then advance in the circuit by hunting for their answer. If they can not find their answer, then they must find their mistake or ask a question. This element of self-check in the math classroom is essential. The directions are, "Find the "p" value in each equation. Use algebraic techniques to manipulate and reduce each equation to its p-value. Do not merely guess and check, especially towards the end!" This circuit can be used in Algebra II classrooms, for test prep, and even in college algebra. Enjoy the sounds of your students' questioning as they work a circuit!
