DD is in Y3 and has always been slow on the uptake with numbers/sums etc but a whiz with reading/literacy. She's started a new school this time (was at infants before and current school is Infant & Jr with mixed year classes, DD currently working alongside Y4) and has brought home her first piece of numeracy homework. Basically it was a list of items and prices and DD had to work out how much change from 100p they would get from each item using a number line and counting on from the item cost to the 100p. She appears to have been shown to count up the the nearest 10 and then count on in 10's to the 100p.
She just completely does not understand it at all and was getting quite upset as she had been working through each one and thought she was doing it right, but when I checked through her answers they were completely wrong. I tried to explain what I thought the teacher was trying to get at but DD got upset again, saying that teacher had told her to do it this way. I'm getting in a bit of a state about this and not sure what to do. Is this the sort of think someone of DD's age (7) should be able to do easily?
I've told her to leave the homework as it is and DH is going to include a note saying that she doesn't seem to understand it. Will the teacher pick up on this a figure that she is struggling or should we request a word with the teacher (not supposed to approach them and drop off/pick up) or leave this until parent's eve (which will be around Oct I think)?
Any advice would be fab, I'm even thinking of looking into Kumon or something for some extra help with the numeracy!!
