So, e.g. if your 5 year-old was currently doing a topic all about insects/ small creatures at school, would you....
a) -chat a bit about it together and point our a few spiders and wood lice in the garden
b) - go through all his books for ones related to e.g. caterpillars/ ladybirds/ bugs and read them all reigiously all week
- go round the garden 'bug-collecting' together
- make playdough bugs together
- print off bug colouring pictures and discuss and label them together
c) say "what topic was it again?" a week after it had finished...
