Great 100th Day of School activity! Students will be timed to see how many repetitions of a certain activity they can complete in 100 seconds. Can either be completed whole group with the teacher timing or in small groups/partners with the students collaborating to time each other. You could also use this as a data collection sheet to create graphs and charts for a group of students. Develops number sense, counting, understanding of time, graphing skills, and is a fun way to keep the kids active and engaged during math!
