CHEM-0-PARDY Unit 1
2
Rules 1. Mrs. Hurley makes all of the rules. 2. In the event of a tie, ruling goes to Mrs. Hurley. 3. Concerns, questions… see rule #1.
3
To play: 1. A team will select an available category and point value. 2. All teams will write a response in the form of a question. 3. The first team with the correct answer earns the points and chooses the next answer. 4. Points will be deducted for incorrect responses. (But only if you are called.)
4
To answer: 1. The team scribe may start writing your team’s response when Mrs. Hurley finishes reading the question. 2. For all responses, all teams will write the response in the form of a question on their dry erase board. 3. When you have finished writing, put down your dry erase board and your marker. 4. Each team member must raise their hands to signify the team has completed their answer. 5. The first team that Mrs. Hurley deems ready will be called on first. 6. The first team with the correct answer earns points and gets to choose the next question.
