I used Math Blaster which is an online computer game for math skills. It's a space mission and very fun and engaging.

My daughter has an amazing memory, so us and the school use that to our advantage with math. She would study one number like +3's all week, I would quiz her and if she got them all right we would move on. She's in 3rd grade now, moving on to multiplication and division and I'm doing it the same way. So, if your child has a good memory this could be a good method.

Not sure I fully understand. Can you send me a link to a see what you're talking about.

Thanks. I will try these or similar
