The “Angry Mother Destroys Common Core” internet meme got my goat when I browsed the comments section. I grant that the actual meme problem was overbearing (it’s the “write a letter to Jack” about subtraction error using the number line). But in the comments I saw a lot of complaints about how the number line approach was not the fastest way to the answer, and thus a confusing waste. Not those commenters’ faults in a way; they are just sticking with the one-right-way paradigm about math they were taught back in the day.
So I yielded to temptation and uploaded a response comment on the meme’s thread, sharing here for (I hope) your amusement:
Apparently to many folks, the Fastest way to get to The Answer is the Point of math. Here are 9 ways to go faster:
1) Memorize lots of formulas – as many as you can.
2) Once it seems to you like one of your formulas can be applied, run it.
3) Even for addition, use a calculator (We all have one in our phones, sweet!)
4) Download a powerful calculator that has lots of formulas pre-coded for you to just punch in a few #’s. Less memorizing!
5) Have your mom do the problem for you (that’s faster, right?)
6) Have your mom just give you the answer (now we’re getting fast!)
7) Have your smartphone solve it (it knows more than Mom!) http://www.nydailynews.com/…/new-photomath-app…
8) Don’t answer the question – heck what difference does it make if you answer someone else’s canned math question anyway?
9) Don’t even bother taking a math class and save yourself years of grief – other people know how to do the math that you can’t do with a calculator or app anyhow, right? And aren’t there lots of people to tell you they never broke out a binomial or even an ‘x’ in their worklife, ever, so what a waste?
Oh, and now that speed has been served, please enjoy your trip into the real world after school, where people get good pay if they can solve real problems via pattern recognition, efficient problem abstractions, and a myriad of hierarchical solution methods, using logical thinking. Within a few months of hiring on, managers know who can solve problems and who is weak. Calculators don’t cut it.
Oh yeah one more thing: in the real world there is no 1 right answer in the back of the book.
My kids will see your kids out in the world competing for jobs. Good luck to them all!
