### Warm-Up Activities:

Pass out dry erase boards to pairs of students or individual students. Students will be using their boards to show their work throughout the warm-up activities. The teacher can begin with a quick review of the rounding concept that they are currently working on in class. Simply go to the rounding drills link http://mrnussbaum.com/rounding_drills/  and then select the appropriate skill review for their specific students prior to playing “Half-Court Rounding”.

Prior to playing the game it is also suggested that you watch the rounding video at the following link as a warm-up for your students. – http://mrnussbaum.com/rounding_videos/

### Main Activity:

Students should watch the instructional video before playing half-court rounding on computers or iPads (http://mrnussbaum.com/halfcourt/). Students will play the “Half-Court Rounding” game either as a whole group or on individual computers. If you are playing as a whole group, split your class in half. One side can be team A and the other team B. Alternate the problems and give points to each team, if the person gets the rounding correct.
