Reflection: Intervention and Extension Polynomials and Factor by Grouping - Section 3: Exit Slip

 

You can see from the first student example of the Exit Slip that the student does provide the correct factors for problems a through e.  However, it does look like that the student continued solving for x in problem c.  Students continually get confused between the instructions to Factor or Solve.  Repeating and modeling the difference between these two verbs is important for student success in this Unit and the next Unit which is Quadratic Functions.  

Another Important reflection about this lesson, is that students need to understand that factoring and multiplying are inverses of each other.  The student that turned in the second example of the Exit Slip made several mistakes which may have been prevented if the student would have checked that the product of the factors was the original problem.  Encouraging students to continually check factors by multiplying them back together is another way to ensure students success with this such important skill of Factoring.

Polynomials and Factor by Grouping

Unit 7: Polynomial Operations and Applications
Lesson 8 of 9

Objective: SWBAT factor four terms of a Polynomial using the Factor by Grouping method and apply it to finding the dimensions of a garden.

Big Idea: To observe that Factoring by Grouping can be used for Difference of Squares, and Factoring Trinomials, but must be the method used to factor four terms.
