I use Conquer Maths (as well as workbooks etc.) as our maths curriculum for my Home Educated children. My Year 4 child who is very study-resistant is just finishing up the year 4 program, right on schedule. Doing his work on the computer suits him very well. My year 1 more scholarly child is just finishing up year 3. I even caught him trying one of the year 13 lessons "just for fun"!!! I love the way that we can dip in and out of the different levels, to go back to basics if they don't understand something, or to move on ahead if they are ready and eager. The short, bite-size lessons are just right for explaining the topics, and the immediate questions reinforce the learning. Unlike other, more expensive programs that we looked at, there are no fancy animations, although the times-tables space invaders has certainly helped them to learn their tables!
