Monster Squeeze is an Everyday Math game that requires students to use a number line. One student picks a mystery number and then the students try to guess the number. The game is essentially a "Greater, less than" game. The monsters squeeze together as our guessing gets closer. My class did a great job!
There is also an online version that you can play.
