I wrote this circuit for my algebra one students as we wrap up the course, although it is structured so that students could work through it cooperatively with very little prior knowledge. It also would be perfect for the beginning of an algebra two course. The 24 questions allow students to take a tour through the landscape of arithmetic and geometric sequences. The questions are progressive in nature (build from easiest to hardest) and the last four are standardized test challenge problems. Calculator use should be minimal (or maybe zero -- you be the judge) on this circuit.
I do not include an answer key since the answers are imbedded in the circuit; it is how students move from one question to the next. This element of self-check is essential because it requires students to ask questions if they can not find their answer. The only thing the teacher needs to do is work the circuit ahead of the students to decide what, if any, vocabulary / notation / concepts should be addressed before the students begin. You will love the sounds of your students as they work through a circuit!
