So…as you may know, using math concept sorts is one of my absolute favorite strategies to get students thinking and talking about math. I often used them sporadically in my units….sometimes as a “kick off” to see what they know…sometimes in the middle…sometimes as a review.
Today I thought I’d use one of my sorts that we didn’t get to earlier as a great test prep review of multiplication and estimation. I thought, “This will be an easy one…a good 25 minute warm up.”
What I had planned to be a basic warm-up turned into a 45 minute, in-depth study! It was SO much more challenging than I thought it would be. Here’s what we did.
Multiplication Teaching Using Math Sorts
This particular sort is a little unusual…it has 24 cards of multiplication problems; students are asked to use estimation to find 12 pairs that have similar estimated products. Simple enough, right? I encouraged students to jot down their estimated numbers to help them–and figured it would be a pretty quick task!
