Exam 1 PBS Review

Trashketball

• Get into 4 groups
• Each group will start with 10 points on the board. The goal is to remove points from other groups.

• Each group will get the opportunity to answer a question. If answered correctly, you will get to earn more removal points by shooting "trash-kets"

• Correct answer, but no trash-kets= remove 1 point from another group
• Trash-ket from 2 point line = remove 2 points from another group or combination of 2 different groups
• Trash-ket from 3 point line = remove 3 points from another group or combination of 2 or more groupsIf your group loses all points
• If your group loses all points, you can earn back points by answering questions correctly &/or shooting a trash-ket
• Correct answer but no trash-kets - add 1 point back to your group
• Trasket from 2 point line = add 2 points back to your group
• Trash-ket from 3 point line = add 3 points back to your group

Other notes:

• we will rotate through groups
• 30 seconds to answer
• must "buzz in" when you're ready for your final answer
• If you answer incorrectly, another group can "steal" your question - first to buzz in must answer immediately

• The group with the most points remaining wins!
