The 100th Day is a huge milestone in the primary grades. This chart can be used on the 100th day to provide students with fun, enriching, and challenging activities all having to do with 100. There are ten centers in total. My class spends the 100th day of school working on these centers the entire day. They get 10 points for each center that is completed. The goal by the end of the day is to reach 100 points. I usually have prizes for those who can do it. Some centers include: draw yourself at 100 years old, write 100 words and complete 100 addition facts. I have included print outs for the centers that require them.
