One of my favourite aspects of educating the girls at home is being bombarded with their wonderful questions all the time. Sometimes they want to know why clouds don't float off into space? or why grass grows in winter when the rest of the plants die?
That said, there are times and places where these questions prove difficult (like in the middle of the night) so we decided to give them a place to record the questions so we could approach them at a more sensible time. I drew a thought bubble on a small whiteboard and stuck it at the bottom of the stairs with a pen, they can write down any questions or draw a picture to prompt them, then during reading time we can have a 'question session' where we can look up the answers.
So far it seems to be working nicely and is a great way to sneak in some extra writing practice.
