Our 100th day of school was last Thursday, February 9th and we engaged in a variety of activities to mark the milestone. These included stringing 100 beads in groups of 10 and looking for hidden pictures with objects arranged in rows of 10, both of which gave us practice counting by 10's. We also played a partner game to collect 100 cubes, practiced reading 100 words, and enjoyed a snack with 100 little morsels. Celebrating the 100th day is not only fun, but I find the emphasis on 100 for a day or two can also deepen children's sense of our number system and how numbers to 100 are composed and written as groups of 10 and additional ones.
