Reposted by Tierney KennedyPat-HEX-myth (love, with a routing number) @patri.xyz · 02/04/2024As an engineer, I urge you to provide formulas. We actively discourage people from relying on memory to do important calculations. That's how you send complex systems into disarray because of tiny avoidable errors where someone just wanted to seem all knowing. 251
Reposted by Tierney KennedyDavid K Butler @davidkbutler.bsky.social · 28/02/2024I think one of the issues with the teaching of something like drug calculations is that experts think it’s just “simple arithmetic” but don’t realise they are actually using multiple different strategies flexibly even in a simple problem. 261
Tierney Kennedy @tierneykennedy.bsky.social · 25/02/2024Make ten is a really fun, cooperative card game. It is played like go-fish, but open handed. You ask for a card from someone else that would add or subtract with one or more of your own cards to make ten.

Tierney Kennedy @tierneykennedy.bsky.social · 18/01/2024What’s the perimeter? I wrote this for year 8s after teaching Pythagoras. I sketched the kite, then added the line across the middle and said “that’s 12 long”. I drew a circle with 15 in the top triangle and said, “this area is 15”, and repeated with 48 for the bottom. They had a ball! #iteachmath 010
