socialising (parentally facilitated i.e. hanging out with a bunch of other HE families at the park)
working on roller skating skills (parentally facilitated i.e. I took the skates to some good tarmac for them to use)
literacy development (entirely child led)
Experimenting with the texture of sand on skin; using sand as an artistic medium; playing with vehicles in sand
PE, including balancing (alone and in pairs)
2 times table (yeah, we all know the 2 times table, but it's still fun to shout out how many wheels a big lorry has when we pass one)
developing narratives, visual imagination, literacy, fine motor co-ordination, computer skills (all child led; aka making cartoons)
That's just this morning.
