Dd yr 5 is below expected standard for maths. I've tried a private tutor once a week but it's not really helping. She needs repetition of the basics but trying to get her to do extra work at home is a struggle. Doesn't help that dd1 yr 6 is a high flyer so doesn't need the same pressure to do extra. I'm wondering about Kumon. Her teacher thinks it might help. Would appreciate any advice! TIA
