Reflection: Positive Reinforcement Order of Operations - Section 1: Warm Up


I didn't think this warm up would take as long as it did.  I knew that they had solved similar problems in the past so I wanted to use it as a preview of what was to come.  

When the majority of the students had the correct answer, I figured it would be a quick conversation about how they did it.  Then, when scanning their work, I found many different entry points.  I knew this was worth discussing.  

The students had less time to practice simplifying expressions with exponents than I planned, because I didn't rush through the valuable dialogue that came from the warm up.

It is important to gauge pacing in terms of the students and their needs.  Then, adjust accordingly.

It was rewarding to see students feeling confident that they could find the "nth" step of this pattern.

Order of Operations

Unit 1: Numerical Expressions and Patterns
Lesson 6 of 13

Objective: SWBAT solve basic algebraic expressions using the order of operations.

Big Idea: When students know to simplify expressions before stressing, they will find complex expressions can be simple when taken one piece at a time.
