Periodically return to the basics of place value. 5th graders are expected to read/write numbers and round to any place value. These concepts are usually taught in isolation, then rapidly forgotten. Consider integrating this work throughout the year. #iteachmath #mathsky #edusky #iteach

'I saw my first 'aeroplane propeller' long before I saw an aeroplane, when the children would shape two long leaves then centre them using a thorn for a pin. Slewed into a smoke column it would whirl itself swiftly upwards in the hot air-current, just like propeller blades.'

One neat math detail: Here I animate adding transformations by right multiplication
previous_iterations * {A, B}
instead of the usual
{A, B} * previous_iterations
Both lead to the fractal in the limit, but the first one emphasizes local changes; the latter, global changes.

Connected Lights is one of my favourite problems to play with because it leads to so many different variations and offers so many underlying patterns and causalities to uncover. #MathSky #StorySaturday

Seems a good day to remark that π isn't something to get all bothered about, but then neither is τ. At least, not *that* τ.
