Seeing this lovely set of playing cards gives me the excuse to air a thought I had a while ago.
As a child I played cards lots. And the skills I didn’t realise I was learning are dead useful for seeing different ways into data, handy if you work in infographics these days: groups, sub-groups, hierarchy, sets, patterns, mental arithmetic, different ways of cutting and rearranging the same set of numbers. Same idea as here.
Add it to the curriculum immediately.
