Do you need some fun activities to do with your students on the 100th Day of School? Here are four activities to help your students enjoy the day while reinforcing academic concepts. The four activities included in this packet are: write 100 words from around the classroom, solve 100 addition and subtraction problems, group 100 stars into sets of 10, and make a fun pair of glasses to wear in the shape of the number 100. These activities can go along with the 100th Day of School Book created by Krista Lynch. Your students will enjoy a fun day of celebration while continuing to practice important academic concepts.
