Give your students engaging practice with the circuit format! Students must simplify algebraic square roots. All variables are non-negative so there is no absolute value needed (i.e. suitable for algebra one). Students hunt for their answer to advance in the circuit. The only prep the teacher has to do is work the circuit before the students to understand the unpacking of the concept. My students love this format -- they lean over effortlessly to help each other and don't want to leave when the bell rings!
