I register my 5 yr old girl in Kumon on 17 Aug 10. I've decided Kumon due to her poor attention in group clsss. I found out that she always likes to talk to other children site next to her (I peep her through door or window during Art class, English class & Chinese lesson.)
Although Kumon does not have tutor, but they dont't allow students talk during the class too. My girl told me she went to the class & starts her math worksheet not even look around as it was always silent there.
I believe practice makes perfect for maths. Her math has seems to improve now and I am happy with her result. Her class is every Tuesday & Friday 8pm to 8:45pm.
Hope this help you.
