    Word Problem Wednesday: Turn Up The Heat on Everyday Math Skills

    By Mathnasium | Added Jan 31, 2018

    This baking-themed word problem helps kids practice and improve everyday math skills, including subtraction and division.

    Do you have sweet everyday math skills? Then it’s time to turn up the heat to practice and improve! Don’t sweat it, take your time to think it through step by step, and this word problem challenge will be easy as pie. (hint: you’ll need to use your subtraction and division skills.) We know you can do it!

    Challenge: Nellie puts a batch of pies into the oven at 6:17 AM. When they go into the oven, the internal temperature of the pies is 60° Fahrenheit. The temperature increases at a rate of 2.5° per minute. If Nellie wants the internal temperature of the pies to reach 160°, at what time should she take them out of the oven?

    Don’t leave the problem half-baked, once you think you've worked it out, check below for the solution!

    Solution: In order to increase to 160°, the internal temperature of the pies will need to rise 160° – 60° = 100°. Since 100° ÷ 2.5° per minute = 40 minutes, it’ll take 40 minutes for the pies to bake. So, Nellie should take them out of the oven at 6:57 AM.

    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.
