## Reflection: Adjustments to Practice Factor Pairs, Arrays, Patterns and Fun! Building factor pairs to 50 - Section 3: Step by Step: Creating the Factor Pair Cards

Before this portion of the lesson, I had planned on using  the Illuminations Website from NCTM that I had used yesterday, called Factorize! This is an easy way to show students how to use their graph paper to find all of their factor pairs and it guides us to how many factor pairs there are for each given product.

Because students did so well with the factor game in our warm up,  I didn't need to go through steps that I had planned to list factor pairs for 21.  I thought I would have to review! I think because the lessons were so thorough in the past two days, and they had practiced last night with their assignment, these students were ready to move into direct instruction.I had checked their homework early in the morning and suspected this might be the case!

My plan was to list factor pairs for 21 and go through the ordering process as we had in the lesson prior to this one. We would have listed 1x21, 2? 3x7 and used the Factorize graph paper to check  our work. I could move right on today!

I didn't have to conduct a whole class review like I planned!
Adjustments to Practice: I didn't have to conduct a whole class review like I planned!
