khan academy is a wonderful site that your child can use if they are having difficulty with a concept in math.  It is free but you have to sign up.  Then you search for concept they are struggling with and they can watch a short video on it.

Your child has access to the math book from home@ http://my.hrw.com

Their username and password are stapled inside the front cover of their agenda.
