100th day of school project.

The 100th day of school can be such a fun celebration! I love explaining to students that they are 100 days smarter and it’s only going to get better. While I keep things educational, I love to incorporate a fun and memorable 100th-day project for the kids to remember as they get older. From crafts to decorations, we like to keep things light and fun.

Do a Fun 100th Day Celebration Craft

If you know me, you know I love doing crafts with my students. These 100th Day projects are awesome to put together, but they are also really funny to read for the younger students.

Students color and decorate their craft templates and then piece them together with their chosen writing prompt. The prompts range from pre-k dotted lines to blank templates. Students can fill in statements about themselves when they are 100 years old, write Happy 100th day or 100 days smarter. Decorate the craft with cotton balls or other materials to make white or grey hair and display on your bulletin boards. You can find the 100th Day of School Crafts here.
