Wow, that's expensive. I was wondering how many kits you have purchased already. If you have 12 of them already for instance, can you start at the beginning and do them again? I have weekly themes because I like knowing that I'm teaching the children a lot of different things all year long, but I tend to repeat them year by year to reinforce the basics as they grow they absorb a little more every year.

But I pick up books for my theme at the library every Monday, search the internet for crafts and ideas for songs, games and lessons. So it doesn't cost me very much to run my daycare. Don't forget that when you are walking outside you can teach as you walk, science is everywhere.
