Making Desmos Elementary: A 1st Grade Card Sort

Hello math geeks!  Welcome back!

I’ve been an advocate for using dot images and visuals as problems for number talks in the elementary classroom.  (You can find a great bank of visuals here.)  I’ve also been an advocate for using Desmos as an instructional tool for letting student thinking drive the classroom discourse.

Traditionally, Desmos has been used mostly by middle and secondary teachers as a teaching tool.  But recently they’ve introduced Card Sort as a way to make Desmos a useful instructional tool for elementary teachers and students as well.  I wrote a bit more about this on my post here.  Annie Forest made some brilliant screencast videos about how to use Desmos here.  Check them out!  She also has a bank of activities (small but growing!) here.

Here’s a link to my card sort activity. 

Numberless Word Problem 2: Data Exploration in 1st Grade

Have you seen the amazing visuals over at Number Talk Images? These pictures are ideal for any teacher looking to get all students talking about numbers and mathematical reasoning, regardless of ability levels. We used this image as a number talk to launch a lesson that focused on first grade students making statements about a data display. Inspired by the work by Brian Bushart and Regina Payne, we used a numberless word problem approach to build and structure discourse about a data display.

I hope that there are other 1st (and 2nd) grade teachers out there that might find this analysis useful if they are looking for strategies to get students talking about their mathematical thinking. We wanted students to produce mathematical thinking, not just consume it. Here’s what we created.
