I don’t get any of it ...

I get the 12, where do you get the 3 to make 15

Assuming 15 is right, where do you get the 5 to make 20

Assuming 20 is right, where do you get the 10 to make 30

Assuming 30 is right, where do you get the 2 to make 32

All there are doing is adding to 12 to get to 32. Guess they figure our kids are to stupid to subtract or our teachers are to stupid to teach subtraction so they just teach addition. How much do I have to add to 12 to get to 32 is the same as 32 minus 12.

"I don’t get any of it ..."

I think they're trying to get the answer by adding up the difference between 12 and 32 in incremental steps. So the starting number is 12, and they add 3 to get 15. Then they add 5 to 15, to get 20. Then they add 10 to 20 to get 30. Then they add 2 to 30, to get 32, the ending number. Then they add all the individual results (3+5+10+2) to get 20. It seems very arbitrary.

I teach at a middle school, where Common Core Math is being taught. Speaking with the Enrichment Teacher, she informed me that her top students are struggling with it. In her estimation they are breaking something that isn't broken.

That along with some other issues in our school have been enough for her to retire early losing her medical coverage.
