    By Mathnasium | Added Oct 24, 2018

    Improve elementary school A plus math skills such as addition, subtraction, logic, and patterns with this word problem challenge.

    We love arts and crafts! There’s nothing so satisfying as making something special with your own two hands. And quite often, arts and crafts require great math skills. This week’s word problem challenge brings these things together and gives students the opportunity to practice their elementary school A plus math skills such as addition, subtraction, logic, and patterns.

    Gather your wits and your skills, and see if you can help Magnus figure out how long it will take him to carve 20 wooden ducks. Take your time figuring it out, and be sure to take your time, and when you're ready look below to check your solution against ours.

    Question: On Monday, Magnus carves his very first wooden duck. On Tuesday, he practices by carving 3 more wooden ducks. The next day, he carves 5 more ducks. The day after that, he carves 7 more, and so on. If the pattern continues, on what day of the week will Magnus carve his 20th wooden duck?


    Solution: Magnus’s pattern follows the odd numbers. According to the problem, Magnus has 1 + 3 + 5 + 7 = 16 by the end of his carving on Thursday. The next day, Friday, he must carve 9 more ducks. Because 16 + 9 = 25, and 25 is more than 20, he must carve the 20th duck on Friday.

    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.
