Some context that may be relevant. Something like the following is not uncommon, at pretty much any grade level:
Teacher T, Student S (not always the same student), Students Ss
T: "I've put the exact steps you need to follow on the board, right here. Repeat that back to me."
Ss: "The steps are on the board."
T: "Great. Any questions? No? Makes sense? Cool, get started!" (walks among students to check work and help as needed)
(10 seconds later)
S: What do we do first?
T: It's on the board. Right there. The step labelled "1". And first on the list. Is there part of it you don't understand?
S: Oh, no, I just didn't know it was there.
(2 minutes later)
T: Uh, are you done?
S: No. I just didn't know what to do next.
T: Did... you do all the steps? On the board?
S: Oh, right! No, just step 1.
(5 minutes later)
S: Mr/Mrs T, what's step 3?
T: Did you check the board?
S: Uhhhhh, oh yeah.
(this happens some more. 6 hours later)
T: (grading papers. Several students missed one or more steps.)
(next day)
S: Why is my grade so low?
T: You didn't do step 4. At all.
S: I didn't know what to do there.
T: (points at list, still on board)
S: Oooooh, yeah.
T: (sneaks whisky from desk to make it through the day without killing self or others)
