Unit Rate Lab
Unit Rate and Constant of Proportionality Lab
Students find their walking pace (simulated, or by pacing the hallway), a lantern's burn rate and a rising tide — then use k forward and backward to find their way out of a dark tunnel.

- Grades
- Grade 7
- Math
- Finding k and solving with y = kx
- Format
- Solo or small groups
- Time
- One class period
- Runs on
- Any browser — Chromebooks and projectors
How the lab plays
- Real and simulated measurements become unit rates.
- Students use k to predict forward and to work backward.
- It's Act III of Numeria and Beyond, without the story.
Skills covered
- Unit rates, including with fractions
- The constant of proportionality
- Solving problems with y = kx
Built-in questions follow the NC Standard Course of Study. You can upload your own question banks for any state's standards.
