What's the expected answer? "Because 2 is less than 4"? Could be "because 20 + 20 = 40" but that seems to be too advanced for these types of tests.
Probably a number line? Draw a line to show it's only 2 jumps to 20 but 4 equally spaced jumps to 40.
As a teacher that's what I would've done at least. Number lines are quite effective at helping kids visualize numbers.
This response doesn't seem to indicate this particular teacher has adequately explained what the expected answer is though.
Sounds reasonable, but the task should be something like "Draw a graph and show why 20 is smaller than 40" or something
Eh, I don't necessarily agree, you're testing a child's ability to come up with a solution moreso than their ability to follow instructions. Other answers are possible, and maybe a student prefers their own way. But one way of doing it, like a number line, should be so ingrained in all students that anyone knows at least that one way of doing it, imo.
I don't think so. The question is so vague that I wouldn't know what to say and be stressed out. For a class room setting where everyone can share their idea it would be a different story but not in a test
