Someone mentioned PSHE, I don’t see how there isn’t just a basic life skills course. Teach kids about cooking and nutrition, teach them about interest rates and mortgages, teach them how things to do with money work. There’s likely numerous other things too, pop it in there with some basic first aid and chances are a few might complain it’s boring due to young minds, but I bet they appreciate it more when they’re older than they do some of the older parts of maths and the like that most never use outside of a GCSE exam room.
