Contradictions and Identities Part 1

Contradictions and Identities Part 1 is a Grade 8 equations activity for distinguishing no-solution equations from identities. Students examine examples where the variable disappears and the remaining statement is either false or always true, then create their own contradiction and identity cards. Writing examples themselves pushes students beyond simply labeling teacher-provided equations.

Use it as a whole-class introduction or guided lesson after students are comfortable solving linear equations. Ask students what the final statement tells them about the solution set and why.
