Math superstars problems 1 to 5::


Math superstar problem 1:  If the 24th day of the month falls on Saturday, on what day did the 8th fall?

Solution:  Students can use a calendar or make a chart with “Su, M, T, W, Th, F, Sa” at the top and begin numbering      backward putting 24 under Saturday. They may also realize that the 17th and 10th fall on Saturdays and count back from the 10th.

Math superstar problem 2:  Together, 12 tigers  and 6 horses weigh 1050 pounds. The horses all weigh the same -- x pounds. Each tiger weighs 55 pounds.

What is the  weigh of one horse?

Solution: Students will probably solve this by first finding the total weight of the 12 tigers: 12 × 55 = 660 pounds. Then   they will compute 1050 - 660 = 390 pounds, the weight of the 6 horses. Then 390 ÷ 6 = 65 pounds per horse.:

Answer: 65pounds

Math superstar problem 3: The sum of 3 consecutive numbers is 405. What are the numbers?

Solution:   Students may use the guess-check-revise method. Some students might know that the numbers they seek are about 1/3 of the total, and approximate the numbers by dividing 405 by 3. This gives 135, which is the middle number.

Answer: 134, 135, 136
