Get ready mathletes, because this week’s word problem is dog-gone grrrreat! We make no bones about it, solving this challenge will help you brush up on your measurement and conversion, as well as other elementary school math skills such as multiplication, division, fractions, and more. Put your paws together and let’s get going!

Question: Spot the dog can jump 3¾ feet into the air. Can Spot catch a frisbee that flies 44 inches over his head?

Take your time and work it out. When you're ready look below to compare your solution to ours.

Solution: One way to solve this problem is to convert 3¾ feet to inches. Three feet is 3 × 12 = 36 inches, and a quarter of a foot is 12 ÷ 4 = 3 inches. So, 3¾ is 36 + 3 + 3 + 3 = 45 inches. Spot can jump more than 44 inches, so he can catch the frisbee.

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.
