This two-variable linear inequalities card sort was created to help my students practice Common Core style matching and problem solving with linear inequalities.
The first sheet of cards (Set A) contains linear inequalities where students should isolate y and then match these to the correct slope and y-intercept based on slope-intercept form. The second sheet of cards (Set B) contains eight graphs for students to use to match to Set A. There are two graphs that do not match any of the cards from Set A so students have to be careful and can not simply think, "Oh, this card is left so it must go with this set." The third sheet (Set C) contains cards with two solutions. This is a great set because one of the solutions matches a number of different sets, but the second solution limits it to only one or two inequalities.
Please check out the preview document to see the format and the type of problems so you will know if it will work best with your students. The zip file contains a doc and pdf so you are welcome to adapt the doc file and make it work best for your classroom. The solutions are also included on the last page of the file.
The way I implement these cards in my class:
1) Students are put in pairs and given Set A and a medium piece of poster paper. I let them work on Set A for about 10-15 minutes (depending on the ability of the class).
2) Then I give the pairs of students Set B (which is on a different color paper than Set A) and let students work on this until they are done sorting all the cards.
3) Once students are done sorting the cards for Sets A & B, they notify me and I give them Set C (printed on a different color) and they work to finish this.
4) The next day of class I spend time debriefing with the students and let them do a gallery walk of their peers' posters.
Please let me know if you have any questions.
