Just that really. How much homework is your year 4 prep / independent school child getting? And how much time do you spend either tutoring them yourself or someone else?
Ours gets 10 spellings a week as per year 4 national curriculum, 1 x maths but she and her chum do it usually during the class whilst everyone else finishes their class work and a small writing project / presentation fortnightly.
My concern is she's getting hazy on the times tables. Trying to do extra work at home is a battle whereas she's very happy to do it if her teaches gives it to her!
