Product Description
Before doing this activity:
• Students should have a brief understanding of solving system by eliminating. I assigned a short video for students to watch for homework the night before. I also did a brief lesson at the beginning of the period for those who did not watch it for any reason.
• You can make multiple copies of each part so multiple groups can work on this at once, or it can be a station with other stations (such as spiral review stations). It does not matter what order students complete problems within each part.

This is great for resource classes as well as mainstream classes. Teaching it this way for the first time this year, I found that my students have been the most successful with using this method. Learning one step at a time through a hands-on activity was extremely helpful for them.

How this is structured:
Part A: (hands-on) Systems that cancel out naturally and do not need any multiplication. Only the first step is done, which is canceling out a set of variable terms and writing the new equation.

Part B: (hands-on) Multiplication is required for each problem. The expectation is that students determine what to multiply by, rewrite the system after multiplying, cancel out the opposite terms, and write the new equation.

Part C: (worksheet) Some of the same problems from the hands-on activities. Problems 1-3 do not require multiplication while problems 4-6 do. This time students are expected to solve the problem for both variables. (It is assumed that they know how to solve one- and two-step equations and substitute numbers for variables.)

This activity includes 2 teacher instruction pages, student direction pages for each part with examples given, 5 - 6 practice problems for each part, and answer keys with worked out solutions for all problems.
