100th Day of School

I love the 100th day of school! We spend a few weeks before practicing how to count to 100.  We count by 1's, but also learn how to count by 10's.  My favorite song is by Jack Hartmann on his Math in Motion CD.  Then for the 100th day, I have the students bring in 100 things so we can practice counting by 10's to 100.  We use the small mats and this year everyone brought in stuff small enough to stack on each circle, but next year, I think I will make the mats larger. We also made 100 day hats and had 100 things to create with during centers.

  Here are some pictures.
