I am wondering how often you switch to new themes. This year, I had a monthly themes (like Living things) and then related weekly themes (plants, bugs animals etc.). I've had two problems with this: 1. I am on my own so constantly changing around the centers to reflect the different themes can be a little much, and 2. I feel like I want to spend more time delving into a subject and maybe even doing some longer projects based on the children's interests. So I was wondering what you all do. How long do you spend on a particular theme? How open do you leave things so you can follow what sparks the children's interests? I was thinking that I might just start doing a general monthly theme, do a first week overview and then follow whatever I think the children might like. I don't know exactly how I'm going to do this... this is purely theoretical. Anyway, this is my first year, and I am still finding my footing as far as teaching style and such, and I really appreciate all your help. Thanks!
