Comparing Systems of Linear Equations: Grade 8 Math

Want to know if your 8th grade math students can tell when a system of linear equations has one solution, no solution, or infinitely many solutions? How about if they know when to use elimination or substitution strategically?

This presentation includes 10 questions (23 slides total) that has students work in groups to determine which statement is true between two given systems of equations. Which system has no solution? Which system has infinitely many solutions? Which system is better suited for the elimination method? Teams must be able to determine the answer through visual inspection, then back up their answers verbally.

Great as a review activity before an exam, or as a mid-unit formative assessment to track progress towards mastery.

This lesson also includes a quick paper/pencil exit ticket students can do individually so you can assess each students' mastery, with answer key included.
