Is the one hundredth day of school special where you teach? It can be as exciting as a holiday! I have found that to keep the party atmosphere at bay, a different routine makes it special, but also a day of learning. So, on day 100, plan your entire classroom time around self-selected learning stations.
Here you will find nearly everything you need for a day of 12 self-selected center/learning station activities based on the number 100.
You just provide the blocks, rulers, counters, etc.
