DD has 4 main teachers - I gave $25 gift cards each to walmart (the only thing close to them). I also bought a $5 popcorn tin for the room. I put a picture of DD on top and used a Sharpie to write Merry Christmas.
we participated in Treats for Teachers & brought lots of food for everyone. We gave the main 2 teachers $15 gift cards to Target. I know it doesn't sound like much, but they have only been there a few weeks & DD leaves very soon.
We are doing a $50 gift card for the main teacher and an assortment of candies in a cute bowl for the room as a whole (four or five "float" teachers come in depending on the day).
A friend told me 1 week extra pay is nice...but we have a sitter so there's just one and my DD is the only kid she watches. So we gave ours $150. Personally, I think it's too much but I'm mad at her right now.
