At my school, our head is very against ability grouping and insists children sit on mixed ability tables. I kinda agree, and as such, have organised my children into 6 mixed ability tables. However, i help me with planning and differentiation, i still like to have some sort of ability groups, they just dont sit in them. For example ill just say circles do this, squares do that. Im planning on doing this for lit and maths, but am wondering how many groups to have? Im thinking just 3. to be honest i dont want many more for my own sanity, and for the childrens!!! Is 3 enough, high middle low, etc?
