I think they are asking too much of you. That's way overboard. Our PTO organizes the week and this is what we are doing:

We sent home a sheet of paper last week and asked the kids to make a card for their teacher. We hung them around the classroom doors Friday after school so that the teachers would see them when they arrived today.

Tuesday: bagels (paid for by PTO)
Wed.: chilli and cornbread -- volunteers are cooking
Thursday: desserts -- volunteers are baking
Friday: small gift -- cute sticky notes (paid for by PTO)
