I wrote this 20-question circuit for a teacher who liked the other two simplifying radical expressions circuit, but wanted something more challenging (for honors algebra I or algebra II level students) that required students to think about the square root of x squared as the absolute value of x.
The problems are progressive in nature and to advance in the circuit, students hunt for their solution. This leads them to the next problem. My students love this format and say things like, "I would do my homework every night if it were a circuit!" The class passes so quickly that everyone is caught off guard by the bell.
I do not provide answer keys because the answers are embedded in the circuit. The teacher needs to work the circuit first to see what kind of notes / directions to do with the students before setting them free on the circuit. In addition, the circuit can be used as guided notes if the teacher wishes. If you ever get stuck, do not hesitate to email me at firstname.lastname@example.org.
