Jeopardy Directions• Any group member may select the first question and students rotate choosing the next
question in clockwise order regardless of points scored.
• As a question is exposed, EACH student in the group MUST write his solution on paper. (No verbal responses accepted.)
• The first student to finish sets down his pencil and announces 15 seconds for all others to finish working.
• After the 15 seconds has elapsed, click to check the answer.– IF the first student to finish has the correct answer, he earns the point value of the question and no
other students earn points.– IF that student has the wrong answer, he subtracts the point value from his score and EACH of the
other students with the correct answer earns/steals the point value of the question. (Those students do NOT lose points if incorrect, only the first student to “ring in” can lose points in this game version.)
• Each student should record a running total of his own score.
• Good sportsmanship and friendly assistance in explaining solutions is expected! Reviewing your math concepts is more important than winning.
