• Get into your groups of 3– Take your notebook– Pencil– Calculator

• Pick an animal that makes a recognizeable sound

• Pick up whiteboard, marker, eraser (one per group)

RULES

• Work the problems in your notebook! • Everyone needs to work on the

problems, not just one SUPER MATHLETE, and everyone else chills!

• Work the problem, hold it up and make your “BUZZER.” If it’s right, you get points, if it’s wrong someone else can get the points!
