Make converting linear equations engaging with this riddle-based matching activity!

In this Algebra 1 activity, students practice converting equations from standard form to slope-intercept form, matching equivalent equations, and interpreting graphs—all while working toward solving a fun riddle.

Students will:

• Convert linear equations from standard form to slope-intercept form
• Match equations written in different forms
• Analyze and match equations to their graphs
• Use their answers to decode a riddle

This activity is perfect for:
✔ Practice or review
✔ Partner work or stations
✔ Early finishers
✔ Homework or sub plans

Why teachers love it:

• Combines multiple representations (equations + graphs)
• Keeps students engaged with a built-in “goal” (solve the riddle!)
• Encourages critical thinking, not just procedural work

What’s included:

• Riddle worksheet
• Matching problems (standard form ↔ slope-intercept form ↔ graphs)
• Student recording sheet
• Answer key
