I was considering various curricula, but I think I have enough materials for facts for a while, plus other things (workbooks, the book "Family Math" and a set of first Grade Brain Quest) to take up at least the entire summer. I just want to get her up to grade level (as opposed to where she and her class are at her school).
Have you ever read Anno's Math Games and it's sequels? They read almost like story books. The n+1 that is being discussed here is represented in a section by a magic machine. 3 birds fly in one side and 4 come out the other. Then 4 dragonflies go in and 5 come out. First you are asked, what does this machine do, anyway? Once you've figured out what this fantastic machine does you are asked, what would happen if the 4 birds flew back through again? And again? And again? Then what would happen if the flew in the opposite direction? What do you suppose would happen then?
I just love this series, because there are no places to write an answer, you can just read it like a book. Sometimes the scenarios are pretty fantastical, like magic glue and the magic machine mentioned above. The three books altogether cover a lot of math concepts. What I love most, besides the art and storybook style, is that the concepts are taught in a way that is anything but memorization. I was always good at memorization in school, and it has served me quite well in a basic way, but purely visual, mental concepts are extremely slippery in my brain, and that is what these books focus on. Wonderful books for first-graders like my oldest daughter.
