]]>I used this question in a benchmark retest in January, and I mistakingly thought J was the only correct answer (I used the state’s answer key) even though I too teach subtraction and addition are inverse operations. The state also expects the students to recognize inverse operations as well. After reading Mathematically Correct’s response, I pulled those tests and found results similar to the state. Out of 23 students, 13 chose J, but 4 chose G and 6 were incorrect. And furthermore, TEA is wrong in their explanation that the other two choices could also be correct. Hogwash!

We all make mistakes and so do they. Fix it.

I still hold a grudge over how the old sixth grade Oregon math tests had question after question about “direct variation” when the STATE STANDARDS and the curriculum I’d been using only used the words “proportional relationship”. Yeah, the second year my kids took it, I knew to warn them they were the same thing, but the first year they hemorrhaged points over it. My kids’ scores were way higher the second year. Was it because I was that much better a teacher or just because I knew about some of the test’s quirks? STUPID.
