This is a cooperative learning activity for students to practice solving one to multi-step inequalities. Students are placed in pairs of two and each student has a worksheet with 15 inequalities. The students have different worksheets, but the answers are the same. To encourage students to work together, there is space on the worksheet for students to write their answers on the other student's paper and to initial once they've reached consensus. This activity took my students 30 minutes and I used it as a review activity for a unit on inequalities in Algebra I. The answer key is included. Please see the preview, this is one of my favorites!
