Math Bowl • RULES • Students will each have a WHITE BOARD , ERASER, and CALCULATOR • After a certain amount of time (teacher decides time limit based on question) the students will hold up their white boards. If they get it correct put a point. If both teams are correct, then both teams get a point. If incorrect the do NOT get a point. • If a Student calls out an answer they do NOT get a point and must go to the back of the line. • Do NOT subtract points for incorrect answers • TIMING= The teacher will time each question….please note that there are MANY questions to get through so about (5-30sec per problem) depending on difficulty level. • At the end of time calculate the points with “partner teacher” ….the winner will move on to the next level. • GOODLUCK!!!!!!
