I spend a lot of time finding and thinking of new ways to have my students up and moving. If you are interested in more ways of doing that, then join our mailing list now by clicking here. 

How to run this activity in your class? I purchased a treasure chest; however, you could just print one from Google Images or project one on your smart board.

Treasure chest

Next, I purchased two locks with 3 number combinations. Mine were two of the ones shown below: I locked one through the treasure chest and one through the other lock.


We are currently working on factoring. Here is a sample from my activity. Want activities like this sent to you every week? Join our mailing list! Click Now.

Give them a problem set:

  • Factor out the GCF:  14x³ – 2x² + 8x  and g^4 + 24g³+12g²+4g
  • Students will show you the work for the problem above.
  • Next give them a decoder clue to use with their answer from the problem above.
  • Decoder Clue – Add the coefficients together from the GCF from problem set #1. This is the first number in the combination.
  • Give them the next problem set.
  • Give them the next decoder clue.
  • Repeat steps until they have the combinations for both locks.

Once they crack the treasure chest, have a prize in their or you could write a note, “I hope you had fun. Your prize is the joy of learning!”
