Agenda
- Number talk: Which One Doesn’t Belong — four curves; every answer is defensible, if you argue from derivatives
- Sketching gallery at the boards — every group a different function, the whole toolkit, no technology until the end
- Gallery walk: audit a neighbouring board with Checking Your Own Work — technology confirms after the argument
- Practise: Curve Sketching Practice, second set
Things to do before our next class
- Journal: which feature of your function was hardest to pin down, and which derivative finally settled it?
