    Word Problem Wednesday: Wake Up Call for Elementary School Math Skills

    By Mathnasium | Added Mar 7, 2018

    Practice and improve elementary school math skills such as division and fractions with this week’s word problem challenge.

    If a rooster crowing wakes you up with the sun, when does a duck wake you up?
    Answer: At the “quack” of dawn!

    Which do you think would be a better wake up call, an alarm clock or a duck? This week’s word problem challenge will give you a chance to answer that question AND practice your elementary school math skill such as division and fractions.

    There’s just no “eggs”scaping the fact that every time you practice math skills you improve math skills! So dive right in and give it a try. When you're ready, check below for the solution.

    Challenge: One farmer sleeps through his alarm clock 3 times every 12 days. Another farmer has a duck that wakes him up 2 out of every 3 days by quacking. Which wakeup method is more effective, the alarm clock or the duck?

    Take your time... don't peek until you're ready...

    Solution: Since the farmer sleeps through his alarm 3 times every 12 days, he wakes up to his alarm clock 9 times every 12 days. So, the alarm clock is successful 9 ÷ 12 = ¾ of the mornings it’s used. The duck wakes up the farmer 2 ÷ 3 = ⅔ of the mornings it quacks. Since ¾ is more than ⅔, the alarm clock is more effective than the duck.

    Before I came to Mathnasium, I could sum up everything I felt about math in one word: 'EVIL!' I hated math. ... Mathnasium has been my safe haven. They truly have shown me the light when it came to addressing my fear and provided me with the tools that I need to rebuild my prior knowledge so that I won't forget it. Math is no longer a subject I shy away from but it is a subject I can boldly accept and understand.
