Elapsed Time Digital Escape Room

Inside the case file

Watch the clock — the right elapsed time opens the door — this Elapsed Time Digital Escape Room walks students through a Thanksgiving day of cooking and travel, calculating how much time has passed to crack each code and escape.

It's fully digital and self-checking, so wrong answers won't open the lock and there's nothing for you to grade. Built for Grades 3–6 with a Thanksgiving theme. Open it in any browser — no app, login, or subscription.
