Most days, the first ten minutes of class are a number talk: one prompt on the board, no pencils, no calculators. You think, then you defend your reasoning aloud while we listen for paths unlike our own. The prompts have grown up with you — waves, growth curves, and dollar signs now sit beside the numbers — but the rhythm has not: there is no single right method, and reasoning is defended in public.
| Talk | What it trains |
|---|---|
| Graph Talks | Reading a story out of an unlabelled graph |
| Estimation Duels | Committing to a number and bracketing it |
| Which One Doesn’t Belong | Naming properties precisely |
| Visual Patterns | Seeing the general in the specific |
| Number Strings | Letting one problem unlock the next |
| True or False | Treating an equation as a claim to test |
| Always, Sometimes, Never | Deciding how far a claim stretches |
| Would You Rather | Backing a choice with mathematics |
Why speak before you are certain? Because Mistakes Are Data.
