Chapter 4 Review
Mr. Hauser
Rules of the Game
• Working in TEAMS, you will be asked to
answer questions from the assigned
chapters.
• You have 30 seconds to write the answer
down on the dry erase board.
• When the teacher says TIME’S UP, a
team leader will stand up and show the
teacher their answer.
Rules (Continued)
• Each correct answer is worth one point,
unless otherwise stated.
• Teams can lose points for inappropriate
conduct, comments, or cheating.
• The team with the most points at the end
of the game wins!
