The 100th day of school is a big milestone for young kids. For parents, it often comes with the same question every year: What on earth are we supposed to send in??
This list includes more than 100 different 100 days of school project ideas that work for preschool, kindergarten, and first grade, using simple materials, flexible formats, and lots of room for creativity. Some are perfect for a 100 days of school poster, others work as a free-standing structure, a wearable project, or an easy homework assignment.

Many double as 100th day of school math activities, build fine motor skills, or sneak in literacy activities without kids even noticing.
Pick one that fits your child’s grade level and personality (and your sanity level).
A Quick Tip About These Ideas Before You Start
Before you glue 100 of anything to a poster board, check your teacher’s expectations. Some classrooms want:
- A 100th day of school poster
- A free-standing structure
- A wearable project like a 100th day crown or plain white t-shirt
- Or just a simple homework assignment sent in on the big day
Knowing the format first makes this whole thing a much better way to spend your time.
