Reflection: Staircase of Complexity Factoring (Day 3 of 3) - Section 3: Guided Notes + Practice


For most classes, this lesson introduces the AC Method for factoring polynomials. However, if you have a group of struggling students you may need an introduction to the AC method before this lesson. Lower students may try to factor these problems the same way they did in the previous less.  Stress to them that it won’t work for these. Since the AC Method works for any trinomial do not spend too much time on the pattern method; introduce the AC method early. Higher students are able to choose the best method by understanding that when the pattern method does not work and they need to use the AC method.

Factoring (Day 3 of 3)

Unit 8: Polynomials
Lesson 8 of 9

Objective: SWBAT factor trinomial expressions where the leading coefficient is not 1.

Big Idea: Students will investigate the relationship between factoring and polynomial multiplication. Students will factor complex expressions by grouping.
