Celebrate the 100th Day of School without losing instructional time! This money-saving bundle includes two print-and-go resources designed for upper elementary grades 3–5—one packed with 20+ academic activities and the other filled with 10 hands-on 100th Day STEM challenges. Together, they give you everything you need for a full day of meaningful learning: math, writing, critical thinking, games/puzzles, and quick STEM challenges with testing and reflection.

⭐ Unlike many 100th Day resources designed for younger students, this bundle keeps older students engaged with activities that feel age-appropriate while still making the day fun and memorable. Use it as a full-day plan, rotate through centers/stations, or pick and choose what fits your schedule.

Why Teachers Love This Bundle

Planning for older students can be tricky, and many 100th Day activities feel too young or require too much prep. This bundle solves that with real learning + high engagement, all in print-and-go format. You’ll have both seat-work style academic activities and hands-on STEM challenges, so you can mix, match, and keep your whole class focused all day.

The Best Part

You get two complete options in one bundle:

• A full academic packet you can use whole-group or independently
• A STEM challenge set that naturally builds teamwork, problem-solving, and reflection

⭐ Plus, both resources are easy to customize. You can use a few pages/challenges or run the entire day from the bundle.
