The 100th day of school is fast approaching (it usually occurs in January or February each year). Many schools across the country celebrate the 100th day of school. It’s not only a milestone, but also a great opportunity for teachers to practice math with their students. This is especially important in preschool and kindergarten, where students are learning their numbers. But it also provides good activities for all elementary-level students.

For example, some teachers will ask students to bring in “100” of something. It could be a collection of paperclips, or macaroni noodles, or buttons. The possibilities are endless! This year, my son, who is in preschool, is bringing in a collection of 100 animal fact cards that we collected from National Geographic Little Kids magazines. We laid out all the cards on the floor and I helped him count all the way to 100. In preschool, most children are only counting up to 20, so this activity is a good way to introduce more numbers. It’s also good to count by 10s with them.

100 Things from Highlights for Children is a cute story about a girl who is trying to find 100 things to bring in for the 100th day of school celebration. This story, along with other great math resources, can be found on SIRS Discoverer.
