11/16 Lesson 2.1.7 (8th grade) Simplifying and Recording Work

1.  Warm-up:  Use Algebra Tiles to compare the following expressions

Which is greater:   −1 + 6y − 2 + 4x − 2y  or  x + 5y − (−2 + y) + 3x − 6

2.  Lesson 2.1.7 (8th grade) Simplifying and Recording Work

• Objective:  I will simplify expressions and record my process
• Cooperative learning activity: Sage and Scribe
• Sage builds original expressions, then simplifies using "legal moves"
• Scribe records simplified expressions, one step at a time
• Switch after completing a problem

3.  Closure:  Problem #1-  Which side is greater?  What information would you need in order to answer this question?  For which values of x would the left side be greater?  The right side?

Homework:  Finish Unit 3 project!
