Dot plots

Target: Count observations on a dot plot.

Language target: Say “dots,” not the axis labels, when counting.

Likely miss: Students count the number labels instead of the dots.

Ask: Are you counting dots or adding values?

If you see it: Each dot is one observation.

Evidence to listen for: The count matches the dots that fit the condition.

Next: If the axis number is given as the answer, cover the axis and count marks.

Observable student moves: names both quantities, uses the represented relationship, and revises after feedback. This companion is not a score.
