Linear Systems Odd Man Out

Students find solutions to linear systems using both methods of substitution and elimination. Each sheet contains 4 problems, three of which have the same answer and one is the odd man out. Students solve, identify the one with the different answer. Great way to incorporate writing in the classroom as well as discourse.

I have used these as a check for understanding after a lesson and as a warm up the following day. There are 12 different versions included, enough to double side and use each day during a unit instruction or as a review at the end of the unit. Or use the simpler versions with students who struggle and the more advanced versions with students who need a little challenge.

I demonstrate with a teaching version the first few times I use these in the classroom to model how to approach the activity and what an excellent answer might look like.

Included:
12 different versions for students.
3 different versions for teaching.
