2. Unit Rate Rivalry

3. How to Play Pair up with someone in the group to play against. For each of the 6 questions, find the unit rate. Show your processes in words and in numbers on your recording sheets. Check with your opponent and compare answers. If your answer is correct and you agree, you each score 10 points. If you do not agree, check with the answer key (on the next slide) and the person who had the correct answer scores 10 points, while the other scores 5 points. Continue this process for all 6 problems, and the Bonus Problem. The Bonus problem is worth 20 points. Whoever gets it correct first, gets the 20 points.
