Due to previous lack of strictness about homework, my 13 year old DS has big gaps in his mathematical skills. I know it would only be matter of going over long multiplication and division methods with him, and repeating lots of examples until it is embedded, but he totally refuses to be helped. The last two nights have been awful - yelling, slamming, crying etc. He also refuses to do it on line. What can I do? He now 'hates' us for trying to help him? Any suggestions?
