Agenda
- Number talk: Estimation Duels — how tall is the gym ceiling?
- Random groups — How High Is That? — out of the classroom, and measure something unreachable
- Back at the boards: fold a square, halve an equilateral triangle — exact ratios with no calculator anywhere
- Consolidate: Special Angles — five angles you now own outright
- Check your understanding — exact values only, no decimals allowed
Things to do before our next class
- Journal: your measured height versus the world’s answer — account for the gap.
