DD is in Y2 and while her teacher says she is working at greater depth in the subject currently, she doesn't seem to be picking up general addition/subtraction etc as quickly as I would expect. She is quite a motivated kid so happy to do KS1 workbooks at home, we play board games etc but it doesn't seem to be helping a huge amount with general rote maths. For example, we've been playing monopoly this morning and she is really struggling with things like giving change for £20 if I needed to pay £14 rent. It seems like that's the sort of thing which should be fairly easy by his age?
Any tips (or apps etc) which can help with this?
