The lockbox activity is something I made for review. I did not have the funds for breakout boxes at the time, so this was an affordable alternative with one toolbox and one lock. I do change the code for every class period! My students request this game frequently. I have included step-by-step instructions of how I organize the game, however you can make it your own.
The cut and paste activity can be used for independent practice, review or with a substitute. It is versatile to be used with individual, pairs or small groups.
