Problem A1

Reflection on the three questions should include the ideas described below.

 a. The fundamental algebraic idea (content) in this video is the notion of inverse function as reversing processes and using inverse operations. b. The teacher expects students to write a function rule to start, with a relationship shown as an equation, and then backtrack to find a rule for the inverse function. c. Students demonstrate their knowledge of the intended content by drawing a flow chart for a multi-step function, drawing the backtracking flow chart, and then writing an inverse function.

 Problem A2 Ms. Mattos asks students to focus on properties of operations, not properties of numbers.

 Problem A3 The students discuss operations and inverse operations when they backtrack.

 Problem A4 The students describe backtracking as reversing a process and using inverse operations. This process helps them decide what to do when they solve equations.
