Welcome to a series of posts sharing how we #Desmosify the curriculum from Open Up Resources/Illustrative Mathematics. You can use this lesson for free, or sign up to get many more activities just like it in our core middle school curriculum!

Here’s how we #Desmosified an Open Up Resources/IM lesson to help students learn to solve inequalities..

Desmosification #1: Create concrete connections.

In the original lesson we #Desmosified, Open Up Resources/Illustrative Mathematics invites students to complete a series of exercises like the one below.

These exercises are likely to give students valuable experience with the subtleties of inequalities. The examples include inequalities that are strict and inclusive, inequalities that include negative and positive values, etc.

We worried, however, that students would spend too much time filling in tables to notice those subtleties. We also wanted to connect the solution of inequalities to a representation that’s more concrete for students than tables.

Here’s how we #Desmosified an Open Up Resources/IM lesson introducing students to equivalent ratios.

Desmosification #1: Create concrete connections.

The original lesson we #Desmosified seeks to connect a student’s understanding of ratios to the taste of a drink. Helping a student connect their developing knowledge to some piece of concrete knowledge is a great way to strengthen both.

Here’s how we #Desmosified an Open Up Resources/IM lesson about vertical intercepts.

Desmosification #1: Connect math to the world and back again.

A conviction we share with Open Up Resources/Illustrative Mathematics is that math learning is more durable and more interesting when students get opportunities to connect mathematical representations.

In their original lesson, OUR/IM invites students to connect together text and graphs.

So we were excited to use our digital technology to invite students to connect graphs and a dynamic animation.
