In this lesson, students will work cooperatively to solve multi-step equations online. The program will allow them to solve the equations and then check their answers. Students lacking the needed skills to complete this assignment will be given an opportunity to work cooperatively in an interactive program with algebra tiles to solve two-step equations. The students will remain in their cooperative groups and complete the problems listed on Handout 1. They will also have an opportunity to present their solutions and the process they worked through to get the solution to the class.
