Mathnasium of SW Calgary - Problem of the Week!
Solve the problem of the week below for your grade level. During your @HOME session, be sure to tell your instructor or email the Math Centre your answer so your ballot can be deposited into your grade level entry box before closing time on Thursday. Students attending "in-Centre" sessions can deposit their ballots in their grade level entry box any time they are in the Math Centre during the week. On Thursday evening (8:00pm), a ballot will be drawn from each Problem of the Week Entry Box and the first “correct” solution drawn from each box will win a Fabulous $10 Gift Card. All other “correct” Mathlete solutions entered will receive “2” extra punches on their Reward Card at the start of their next session in the Math Learning Centre.
