If you are looking for some great Thanksgiving ideas check out this Mommy School Pack from Oopsey Daisy. She puts a ton of work into her packs and provides so many ideas!
2 Teaching Mommies also provides another great pack of worksheets to use all based on Turkeys!
Itsy bitsy learners provides quite a few ideas for Thanksgiving on the page linked here :- )
I'm sure there are more out there but for now, these are the key ideas I've found! I plan on printing many of the ideas and either using them this month or having them on hand for next year :-)
