Christmas CSI Digital Math Mystery GAME Activity. Your students can play the Case of The Zombie Elves in a digital game format. This resource is designed to be played on any device with an Internet connection (please read the technical tips section and try the free clue below to see if it works for you).

Mystery meets an escape room with this style of game. Your students will need to discover passwords at the end of each clue in order to access the next clue. Your Teacher copy will contain all links and passwords.

-------------------------------------------------------------------------------------------------------------------

Implementation Suggestion: Turn it into a competition to see who can solve the mystery first in your classroom OR set a timer with a limit that everyone must aim to beat to solve the case (or single clue if you prefer to break it up into smaller chunks).

• After clue 5, your student will be required to select the culprit!
• A Bonus math round will begin after selecting the culprit.
• A short video clip at the end of the game.

Implementation suggestions

There are many ways to use this resource, some include:

• Complete as a whole class on your Interactive Whiteboard. Students take it in turns to answer the questions.
• Assign to your students to complete independently or in pairs on a device. This could be something they do as an early finisher task, during your math block, or for homework.

Sharing with Students

There are a few ways you may choose to share the game with your students:

• The student pages with clickable links are available in EASEL by TPT. When opening Easel, choose which math level you want to keep (top corner marked L1, L2, and L3 for math levels) and delete the other level pages before assigning the game to your students.
• Assign the Google Slide link provided via Google Classroom
• Email the game links to your students.
• Use the QR codes provided for students to scan. These can be printed or shown on the IWB for students to scan from.
• Do as a class on the IWB with your access to the links only.
• If all of the above fails, or if you need help, you can send an email to me and we can try to resolve the issue.

After completing a clue, students will be given a password to unlock the next clue link.
