The 100th Day of School is a big milestone in kindergarten, and it’s such a fun chance to celebrate how far our students have come! If you’re looking for ideas that are meaningful and manageable, this post is full of classroom-tested favorites I’ve used over the years. You’ll find hands-on math and writing activities, a simple 100th Day science experiment, quick 100-second challenges, and engaging seek-and-find activities to keep students focused and excited.
I’ve also included easy snack ideas, fun treats, and personalized certificates that students love taking home as a keepsake.
