Can you give me some ideas? We are not home educating but we live in Germany and he is still in kindergarten so no formal education yet. He won't start school for another year and a half.
He can recognise all one and two digit numbers and add and subtract small numbers (e.g. 2+3 is fine but 3+5 stumps him a little bit, and anything involving adding more numbers than he has fingers is incomprehensible)
I don't really know what sort of thing to do with him? Looking up online just brings ideas like number recognition which he's well past, and cooking/baking, which we do anyway although we don't have scales at the moment. A question came up on a game he was playing about percentages, he can see that 15% of an enemy's total health is a big chunk when they have full health (this is just a doctor who puzzle game, not a violent game!) but I was trying to explain to him about it being a small portion of their health when they only have a little bit left and he didn't understand. Are percentages too complicated, or fractions? If so, what kind of building blocks do they need to understand those kind of concepts - division and multiplication perhaps - where would I start with those?
Science I suspect he means "add things to other things to see what happens" and we've done the bicarb and vinegar one, anything else good?

I’d use a cake and cutting cake to show simple percentages.
Division is sharing an amount between people, so 10 sweets shared between 2 people is 5 each. (or Lego bricks, because they are plentiful and real things that can be physically divided up)
once he has that I would probably try to show that the 10 sweet are 100% of the sweets, and 5 is 50 percent, half of the sweets and so on.
