Ruler Measurement Christmas Digital Escape Room

Inside the case file

Lock the lesson and hand over a link. Your students step into a festive Christmas workshop where every locked door asks them to measure a Christmas tree with a ruler. Read the length, reveal the code, and measure your way to the exit.

It's a no-prep, self-checking review game that runs in any browser — no apps, no logins, no printing. Just send the link and let them race the clock.

The mission

Santa's workshop is locked up tight for the season. The only way in is to measure each Christmas tree with the ruler, read the length, collect every code, and crack the final lock before the sleigh takes off.

How the escape room works

• Open the private link — no app or login required.
• Work through a series of animated ruler-measurement challenges.
• Each correct answer reveals a code that unlocks the next room.
• Wrong answers won't open the lock, so the room checks itself.
• Crack the final code to escape and win.

What's included

• An interactive escape room hosted on a private site — animated, with randomized answers for replayability.
• No Boom Cards, Google Slides, logins, or subscriptions.
• A PDF containing your private access link to share via Google Classroom, email, or any LMS.
