Thanks to Twitter (Nathan Kraft?) I came across this video to use as part of an introduction to ratios. Nice bit of humour/relationship insight thrown in for good measure 🙂
There’s also Dan Meyer’s task on ‘Nana’s chocolate milk‘ that looks at the idea of ratio/proportion… Used in 2020 as part of an assignment task – I think it worked quite well!
Here was a side activity on desmos I used: ‘Balloon Float‘ working on ratios
A Robert K activity on rates and ratios is this ticket one.
