1. ZAP! Cumulative Assessment #4 Review Game

2. INSTRUCTIONS Each team will answer EVERY question on a sheet of paper.
We will still take turns to answer aloud.
If the turn is yours and your team is correct, you receive the full point value of the question.
If it’s not your team’s turn and you’ve answered correctly, you receive half of the point value of the question.
If the turn is yours and your team is incorrect, every other team with a correct answer receives the full point value of the question.
ALL incorrect answers receive ZERO points.
