Today's Common Core Failure

[billroper]

On Katie's math worksheet for today, we find the following assignment:

Write a math problem that uses the word time interval.

The question for you: what is wrong with this question?

I gotta talk this out for myself...

Is this like a Kessel Run?

Also, that's two words, not one.

...writing a problem that uses words sounds more like an English assignment.


*goes to look up Time Interval*
https://www.splashmath.com/math-vocabulary/time/time-interval
Difference between the occurrence of two events measured in time.

...........what. What does that even mean. What.

Okay, http://www.mathsisfun.com/definitions/interval.html is better, defining Interval. And one of the definitions is "A definite length of time marked by a start and finish." So presumably a Time Interval would be an interval of time. (One moment whilst I go into a prescriptivist rage.) (Okay, back.) So the assignment should be: "Write a math problem that involves time."

...I'm gonna go have a prescriptivist rage again.

Aside from calling a phrase a word, this is more of an English problem than a math problem.

My answer to the assignment:

"How many words are there in 'time interval'?"

And Gary for the win! :)

While the grammar is wrong the practice is good. Having students develop math problems helps them understand how to apply math to their life.

I would agree that the idea is a good one. I'm just getting tired of things that haven't been proofed properly, let alone tried out on actual students.

Katie had a math sheet a few months back that started out with an example (as they tend to do) showing a square that was 10 cm on a side that had an area of 100 square inches.

Um, excuse me?

Fair, I've just seen common core getting a lot of flack, and at least on math it's pretty solid. I can't speak to the producer of the worksheets.

Wow! I had no idea Katie was ready for calculus and integration! ;-)
