Picture Graph Read

Watch: Watch whether the learner enters 3 after comparing the two named rows. That response is decisive evidence that the extra pictures were found but the key was not used.

Misread: Responses 24 or 36 show a team-label misread; 7, 42, or −18 show that the comparison action was misread. Responses 3 or 6 show the learner answered with a picture count or the key instead of the bottle difference.

Curriculum: Reads a scaled picture graph and solves a one-step “how many more” comparison by combining the symbol-count difference with the key value.
