YouTube videos of Monty Python, Mr Bean etc. Mythbusters, Qi, Top Gear.
Comedy programmes bring up all sorts of topics to do with our society, not suitable for younger children but cover a lot of PSHE once they are older!
Board games, Cluedo, Monopoly, Scrabble, roulette.
Card games like vingt et un.
Anything involving chatting, using language, challenging ideas, what if discussions, honest discussions about anything. Using vocabulary for real is the top tool in our house as honing and enjoying language is the key. All those concepts get our brains working and arguing/discussing/chewing things over is just the best way to get to know each other and what we think and why.
Listening to the radio in the car leads to discussions. It could be of what the 70's were really like or what we think of Lady Gaga, why potholes happen or what on earth that lorry is doing.
Genuine chats about what is happening rather than staged topics work in this house. There is always loads of data to work from right in front of us. Mine can tell a false approach a mile off!
Can you tell we have hfa in our house?
