I let Jake cut out the people and food cards. He loves to cut and is getting much better but skill needs a little supervision. The best way to introduce cutting is to allow your child to cut blank paper. Having them cut lines are great but not a first step. Let them get the feel of the scissors and get used to opening and closing the scissors.
After each piece was cut out I let Jake go to it on his own. He knew just what to do and glued each piece int he correct spot. While he was working we discussed Pilgrims and Native Americans. He does not really have a reference for them or really for Thanksgiving.
