The Midpoint Formula Visualized for 9th Grade
A station-rotation activity for 9th graders that walks through the midpoint formula as a mean of coordinates, building skills in coordinate geometry and averaging. It is designed as a Tier 3 MTSS station with intensive scaffolds, including step-by-step breakdowns of adding and dividing x- and y-values separately.

Teacher Guide & Tips
- Use this as one station in a small-group rotation, with a student-facing time of about 15 to 20 minutes so the group can cycle through the other stations.
- Discussion question: Why does averaging the x-values and y-values separately give the halfway point, and how is that like finding the mean of a data set?
- Scaffold for struggling readers: Have the student work one coordinate pair aloud, saying each step (add, then divide by 2) before writing the answer, and check it on a number line.
- Extension for advanced students: Ask them to find the endpoint given a midpoint and one endpoint, and explain why the same averaging idea works in reverse.
- Estimated time: about 15 to 20 minutes, plus a brief debrief if the group needs one.
