Reflection: Rigor Getting Ready to Quiz: The Greatest Product Game - Section 1: Warm Up: Drilling factor pairs for numbers 51-100


I am so surprised to see students start to really fluently work factor pairs. I never pushed factor pairs beyond 50 before. I have never incorporated in a warm up or daily fluency plan before. My whole team is getting the same result. Pushing this rigorous thinking is paying off!

As I talk with them about how they are thinking of them during their listing, I am hearing them say their divisibility rules are the main strategy. Prior to Common Core, we NEVER talked about factor pairs and thought about the product first. I see how this supports understanding of the inverse, understanding how the real world may group from a situation where they have  a total to divide. While drilling math facts by rote is still used in third grade, it is starting to leave the focus. Thinking about facts and their relationship to the product, thinking about prime and composite, and thinking about how many different ways we make a product is taking over. It produces a valuable and functional fluency for our students.
