Finding Slope from Two Points Practice
By Gina D.
A practice set for 7th graders that teaches slope using the two-point formula, with a worked example that walks through labeling, substituting, and simplifying, followed by independent problems. It builds fluency with rise-over-run reasoning and the coordinate plane, and works well as a focused skills block of roughly 30 to 45 minutes.
Customize for your classroom
Teacher Guide & Tips
- Use this after students have been introduced to the coordinate plane and the idea of slope as steepness; it works well as guided practice in a 30 to 45 minute block or as independent homework.
- Discussion question: Why does it not matter which point you call (x1, y1) and which you call (x2, y2), as long as you keep the order consistent?
- Scaffold for struggling readers: have them write the coordinates in a labeled table first, then substitute one value at a time into the formula before simplifying.
- Extension for advanced students: ask them to explain why a horizontal line has slope 0 and a vertical line has undefined slope, using the formula to justify each.
- Estimated time: about 5 minutes to review the worked example and 20 to 30 minutes for the practice problems.
