What are number talks you ask? They are a wonderful low floor, high ceiling task that allows everyone the opportunity to share their thinking. Here is a Wakelet of resources I have compiled from the interwebs. I use Fawn Nguyen’s Visual Patterns a lot! A great book I recommend reading is Making Number Talks Matter by Cathy Humphreys and Ruth Parker. I’m sure there are others, but this is the one I read. There are many videos, blog posts, and ideas if you just google Number Talks. I like that Number Talks strengthen numeracy and allows students to see that everyone approaches problems differently, which is the wonderful thing about math. Many students, because of how they have been taught, think there is only ONE way to complete a problem.
As I mention in my book, Make Math Not Suck, I want my classroom to be a safe space. Because of this, I like to keep responses like this anonymous, allowing students to share if they feel comfortable. I started trying to do number talks in PearDeck using the drawing feature. The problem I ran into was wanting students to be able to draw OR write to explain their thinking.
Enter Desmos. With Desmos, you can give students the option to type or write. And when you are working with patterns, they can draw right on the pattern.
We move to hybrid learning this week. Half of my class will be in person and half will be joining by Zoom. I think Desmos is going to work well for our Number Talks in this situation. I can still select student responses to share on the screen that both in home and in person students can view.
If you aren’t using Number Talks, do a little investigating. I think you will find it gives students confidence, it allows you to see gaps in their number sense, and it helps students learn new strategies.
