These graphs have no scale on them, and that is the question. With numbers on the axes a student can read a value across; with none, the only thing on the page is the SHAPE — which is what 8.F.B.5 asks for.
Every other graph on this site is answered by reading a value off it. This one cannot be, on purpose. A scale would turn “is it increasing?” into “is 40 bigger than 20?”, which is arithmetic a second-grader has, and the standard would be met by nobody.
Why this sheet works
The wrong answers are real misreadings, not random phrases. Every question offers the run REVERSED — the mistake a child makes reading right to left — and the run with its first move flipped. A bank of unrelated shapes would let the answer be found by elimination without looking at the picture twice.
How this one works
One question from a sheet like this one, worked a step at a time — with a sentence saying what just happened and why.
The axes have no numbers. Circle what each graph does.
