In honor of 100 days of school, have a mad hatter party. Send a letter home to parents asking them to help their child decorate a hat in honor of the 100th day of school. The hats can be silly or they may want to glue a hundred of something on their hats. My kids always come up with interesting things and tPi ero means nothing. The children laugh and tell me none.
None is zero.
I have a super hero with the number zero on his shirt. Everyday from then on we count the days of school. The children love to count. They can't wait to get to the next Zero the Hero day.
