Math problems of the week: Common Core-inspired fractions problems

From CommonCoreSheets.com:





Extra Credit:

Within CommonCoreSheets.com, the problems on converting fractions to decimals don't get any more challenging than these. Are students missing out on anything if the only fractions that they're ever asked to convert to decimals have denominators of 10 and 100?

The maker of the worksheet was just following the standards (http://www.commoncoresheets.com/FAQs.php, http://www.corestandards.org/Math/Content/5/introduction/). Why would anyone need to understand decimals beyond those necessary to buy an iPhone and contract, anyway? They can just look up that harder math stuff on their phone when they need it! (Unless they're too busy playing Candy Crush or watching YouTube videos....) Only geeks need to know how to convert grams to kilograms, anyway.

Without long division or a calculator, what else is there?

Long division is to difficult for the poor little things, to stressful, might turn them off to math, and calculators make it too trivial to bother with.

Interesting that they have gone back to drill...a 20 problem exercise is a lot.. And the instructions are above grade level.
