We were SO inspired by Hope King's spy lab classroom transformation, and we wanted to bring that idea to our kindergartners with a 100's day mystery.

The problem: Zero the Hero was taken by Devious Agent 99 in order to stop the 100th from day from coming. Without the number zero, it will have to be day 99 over and over again.

The premise: Your students will turn into secret agents as they receive their secret agent badge upon entering the classroom. You will play a special PowerPoint presentation (for Mac users) or a YouTube video (for PC users) with a ransom note being read by another secret agent that will "self destruct" after it's heard!

The missions: Your secret agents will work through several missions (all involving the number 100). After they complete a mission, they are able to open up a clue from Devious Agent 99. The missions include:

✷ Writing numbers to 100 (using invisible ink or highlighters)

✷ Cracking the code using giant 10 frames (making 10)

✷ Bowling to 100

✷ Fingerprint science

✷ I Spy Numbers (Magnify It)

✷ STEM with 100

✷ Minute to Win It Activities (with the number 100)

✷ Making spy potions and "Hot on the Trail" Mix

Once your agents have collected all of the clues and put them together to figure out where Zero the Hero is being held, your agents will be off to look for him! Instead of finding Zero the Hero, they will find a special treat left as a reward for saving 100's Day.

This will be a 100th day of school that your students will never forget!

Here's what other teachers had to say!

Kelly D. said, "This was the most fun I've had celebrating the 100th day of school EVER! The class was completely enthralled from the moment they entered the classroom. I can't wait to try another theme day!"

Heather G. said, "This 100th day was EPIC! My students were blown away. From the ID badges to the recording folders, everything worked so well. They do not remember a lot about Kindergarten... but they will remember this day! My admin says she wants to go back to classroom teaching so she can do this kind of fun stuff."

⭐ You can go all out with black lights and yarn, or you can keep it simple with just the Spy Headquarters sign on the door. It's entirely up to you! You can do all of the centers or even just a few of them. Check out our blog www.kinderbrations.com to read about our entire day in more detail.
