cooking with DGC

I bake with my four year old, she loves it. We work on developing language and maths skills, without it seeming like a school lesson. eg, counting, weighing, predicting what comes next, what I've forgotten to put in etc. Children learn so much more when they are having fun.
My granddaughter has her own set of mini utensils.
As teacher, I would suggest going easy on the heavy stuff, like complex carbs
Just enjoy the time with them. There will be a lot of incidental learning without you even realising.
I would however, ask them to tidy up and do the washing up. Another life lesson.

My 7 year old grandson loves all sorts of baking. Cakes, tarts, biscuits and pizzas.

Don't make it too schooly for them. Just enjoy it. Bake flapjacks and muffins which they'll love as a treat. They can make their own pizza base and choose what toppings to put on it. Making bread is another good idea though this needs patience while it rises. I have always baked with my DC and my DGC. We make a great big mess but have alot of fun.
