Unit 1, Day 10

Agenda

1. Number talk: Estimation Duels — how high did that ball really go?
2. Random groups — the highest point of $h(t)=-5t^2+20t+1$, and nobody has said the word vertex yet
3. Consolidate: Quadratic Functions Revisited — completing the square as a transformation story you already know
4. Check your understanding — one maximum, found two different ways
5. Gallery work time — bring questions, not excuses

Things to do before our next class

• Gallery due next class — run Checking Your Own Work over it first.
• If Grade 10 feels far away, Getting Help and How to Study for Math are your next stops.
