"Eureka Math" -- Am I wrong to think these "incorrect" answers are really stupid?

My daughter's school has adopted "Eureka Math" for this year. In general, I'm a fan of the concept of teaching math "understanding" rather than just memorization (I see far too many adults who know that 5x4 = 20 without understanding when and why do to that calculation.)But this is making my blood boil. Obviously, I don't give a damn about the "grade" (she's in 3rd grade, I'm fairly certain an "x" on a math worksheet isn't going on her Permanent Record), but I'm actually very concerned about the pedagogy.The entire point of this worksheet is to drill home the fact that multiplication is commutative. In the first problem, she was told to draw an array (that's how Eureka teaches multiplication understanding) that represented 8 pages in a photo album with 3 pictures on each page, using circle. She drew:00000000 00000000 00000000 And got half credit because "that is 3 pages of 8 pictures." But it isn't -- not if you view each column as a page and each row as a picture in that page! The entire point of the commutative property is that those are the exact same thing. (FYI, my daughter also -- correctly -- explained to me that she initially tried to do it with the rows being pages, but there wasn't enough space given for 8 lines -- so she actually demonstrated understanding by realizing she could do it in rows and still arrive at the same answer.)She then got half credit when asked to do the multiplication problem for writing:3x8 = 24 I suspect (although it's not stated) that the "correct" answer is "8x3=24". Same thing for the next problem, when our word-problem protagonist adds two more pictures to each page. "3x10=30" is apparently only half right.Almost hidden on the page are the four other x's. When asked to figure out how much money someone makes from recycling 4 cans @ 3 cents/ea., "3x4=12" is apparently 2/3 wrong (as opposed to, you know, entirely 100% correct).Isn't this actually teaching the exact opposite of what a lesson on commutative property should be? DAE find this as infuriating as I do? Am I just a curmudgeonly old man who wants you off my lawn? Thoughts? via /r/Parenting https://ift.tt/2l5iRON
