Why you'll love this

Your students will play the role of a pirate trying to find the location of a treasure. You'll play a video to set the stage, and then your students will solve 18 problems involving systems of linear equations. Each solution unlocks part of a code with the location of the treasure. Play the answer reveal video at the end for an exciting finish!

It's print-and-go and the included videos make it effortless — great for end of unit review, independent practice, group work, or even an emergency sub plan!

What's the math skills practiced?

There's 18 problems total, with 6 problems per part:

  • Part 1: Solve systems of equations through substitution.

  • Part 2: Solve systems of equations through graphing (grids provided, some questions not in y = mx + b form).

  • Part 3: Solve systems of equations through elimination (some problems require moving terms around, no multiplication required)

What's included?

This codebreaker product is a compressed zip file that contains two videos and a 10-page PDF document. Simply download, unzip, and open up the folder with all the files!

How can I use it?

Here's one way you could use it in your classroom:

  1. Play the introductory video. Our animated video sets the stage, introducing students to their role of cracking the code to complete the mission.

  2. Work alone or together. Students solve 18 problems, and get immediate feedback. Students match their solutions with symbols in an answer bank. If students can't find a symbol, that's a nudge to redo the problem.

  3. Check the answers. You can play the answer reveal video or just walk through the answers with students, or pass out a copy of the included answer key for students to check!
