My son finally gets this. I had just stopped except for reading to him. Now we have A, B, C and he does between 30-40 pages a day. So which books are next? Do you just go in order I see listed in the back are 1/2 books.

The 1/2 books are extra practice if they need it. Just start at 1 and proceed from there. If he need more priactice after finishing a book, thne buy the 1/2 one of the same number.

ok, thanks :)
