THANK YOU for your interest!  The goal of the 2019-2020 Math Olympiad Club is to stimulate enthusiasm and a love for mathematics through math problem solving contests. The Math Olympiad involves 5 math problem solving contests from November thru March for a team of no more than 25 Wilson Wims students from 5th grade.

An e-mail will be sent to all families with the results no later than Monday, October 21th.  

Club Activity Dates: Monday starting October 29 to March 11
Tournament Date in April.

Students will be working to solve 5 word questions in 30 minute individually. Teacher or parent volunteer will provide hints and answer guides afterward for discussion.

Sample MOEM Question:  David removes 30% of the water in a jar. He then removes 40% of what remains in the jar. What percent of the original amount of water is now in the jar?

 ANSWER:

METHOD 1: Use the percents remaining
When 30% of the water is removed, 70% remains. Then when 40% of that 70% is removed, 60% of the 70% remains. Thus, 0.6 × 70% = 42% of the original amount that remains in the jar.

METHOD 2: Use a convenient example
The answer will be the same no matter how much water the jar starts with, so assume the jar starts with 1000 mL of water. When 30% is removed (that is 300 mL) then 700 mL is left. Next, 40% of 700 mL = 280 mL is removed, leaving 420 mL in the jar. Thus 420 mL ÷ 1000 mL = 42% of the original amount remains in the jar.
