Write the answer to each of the following questions on your paper. When instructed to do so, show the answer to the people at your table. Without talking choose one answer and write it on the white wipe off board. Then flip the board upside down and wait for the teacher to say “the answer is…” At this time, hold your answer up so that the teacher can see the answer that was recorded. If you got the answer correct, record one point for your table and clean the board off for the next question. Remember: Don’t talk and give the answer away to another table!!
