For all you dummies that can't understand simple "common core" math
here's an example.

Agree! I'm so glad we homeschool and bypass this kind of nonsense.

Make sure we have a "Clean Up Team" on standby when MR2 gets here.
It's gonna get messy.

Looks like they are being taught to make change at McDonald's or Wal-Mart.

Looking at the picture of the new math you posted I found myself thinking, why not just bypass 15 and add 8 to the 12 to get to 20 and skip going to 30 and just go directly to 32 by adding 12, but then I thought, why do all of that when you can just add 20.
I was first introduced to this new math a few years ago when I tried to help my kids with their homework. I was always pretty good at math but when they showed me this, I asked why go through all that trouble when this other way is much easier? They said this is the way the teacher wants us to do it. Try as I might I can't get them to do it any other way, much less do any math in their head, or even stop counting with their fingers. Don't know if that's a biproduct of this new math or if my kids are just really bad at math.

I have been meaning to post this for awhile and it looks like the time is now right . . .
The New, New Math
I purchased a burger at Burger King for $1.58. The counter girl took my $2 and I was digging for my change when I pulled 8 cents from my pocket and gave it to her. She stood there, holding the nickel and 3 pennies, while looking at the screen on her register. I sensed her discomfort and tried to tell her to just give me two quarters, but she hailed the manager for help. While he tried to explain the transaction to her, she stood there and cried... Why do I tell you this? Because of the evolution in teaching math since the 1960s:
1. Teaching Math In 1960s
A logger sells a truckload of lumber for $100. His cost of production is 4/5 of the price. What is his profit ?
2. Teaching Math In 1970s
A logger sells a truckload of lumber for $100. His cost of production is 4/5 of the price, or $80. What is his profit?
3. Teaching Math In 1980s
A logger sells a truckload of lumber for $100. His cost of production is $80. Did he make a profit ? Yes or No
4. Teaching Math In 1990s
A logger sells a truckload of lumber for $100. His cost of production is $80 and his profit is $20. Your assignment: Underline the number 20.
5. Teaching Math In 2000s
A logger cuts down a beautiful forest because he is selfish and inconsiderate and cares nothing for the habitat of animals or the preservation of our woodlands. He does this so he can make a profit of $20. What do you think of this way of making a living? Topic for class participation after answering the question: How did the birds and squirrels feel as the logger cut down their homes? (There are no wrong answers, and if you feel like crying, it's ok).
6. Teaching Math In 2010
Un hachero vende una carretada de maderapara $100. El costo de la producciones es $80. Cuanto dinero ha hecho?
ANSWER: His profit was $375,000 because his logging business is just a front for his pot farm.
All that being said I do teach 'new math' but I assure you it does not resemble anything discussed on this thread. And while I do at times make use of 'old school' rote learning in my classroom, my goal is to have my students: understand and apply math concepts that are found/used in everyday life, have them explain their work/ideas by using pictures, numbers & words (all classroom work is done on a large piece of poster paper which eliminates the need for textbooks and notebooks) and hopefully make connections with other math concepts so that their math skills will increase even more. Problem solving is crucial in my classroom.

Following MR2's "math", this could work to your advantage.

Another example of the "Common Bore" excuse for math. I didn't know whether to laugh or cry. I think I just wound up confused...
