This is the teaching course. Students learn the ideas before going to the separate four-version practice test page.
Course Flow
Students should move left to right. Each station has a diagram, a boundary misconception, and a short drill.
| When students see... | They should think... |
|---|---|
| same type compared to same type | ratio |
| different units with "per" | rate |
| map or drawing to real life | scale factor |
| one part of a ratio is known | find one ratio part first |
Lessons
