# Solving Inequalities Card Sort

In my Math 1 (not ready for Algebra 1 freshmen) class, we are working on solving and graphing inequalities. Today, my students were working with multiple step inequalities – some two-step, some with variables on both sides, and some with parentheses. I had students work in pairs and they were given twelve sets of cards, mixed up in baggies. There were twelve problems, twelve answers, and twelve graphs in each set. Their task was to match problem with answer and graph. I gave them this work page to show their work on:

We had about 25 minutes or so in class to work on this. Many students got through 6 or so. When I printed the cards, I printed them on colored card stock and used a different color for each type (problems in one color, answers in another color, and graphs in a third color).

Students in both classes worked fairly well. I had hoped they would get through more problems. I think the most anyone got through was eight. In fact, I was a little nervous that they would get through all twelve and still have additional time. Part of that may be that we spent more time than I had expected reviewing homework from the previous night. The file has twenty-four sets (problems, answers, graphs) and I mixed up the problems in the baggies so that each pair would not necessarily have the same problems. I am contemplating having students work on the problems again tomorrow for additional practice, but I think I will wait until I see the results of an entrance card as they come into class and make a quick decision at the beginning of class. Since I already have the cards ready to go, it would not be a big deal to have them practice again if the entrance cards show they need the additional practice.

What software did you use to create the inequality graphs? It looks awesome! Thanks for sharing!

Hi Kasey!

I created them in Word, using the drawing tools that were available. Thanks for the complement!

I’m confused…24 sets, but 12 problems?? I love card sorts and want to use this, but can you explain a little more?

3. Lisa says:

I have 24 problems prepared but only gave students 12 problems to work from. I didn’t want adjacent groups of students necessarily working on the same problems. The year I did this, I had issues with students copying each others’ work and moving on without *really* having done the problems. So I made extra sets and mixed up the sets so that groups who were next to each other didn’t have all the same problems and then they would focus more on doing the problems they had.

This is going to be perfect for me next week! Thanks <3
