Success: Identify explanatory and response variables on Card B and plot all six pairs with labelled axes.

  1. Notice · 3 min. Hold up “hours = 3, visits = 9”. Ask how many dots that pair makes. Exactly one.
  2. Model · 5 min. Put hours on horizontal x and visits on vertical y; label units and plot (1,8). Explain that choosing explanatory x is a modelling choice, not proof of cause.
  3. Try · 6 min. Learners plot or tactile-place the remaining five coordinates from Card B. A screen-reader learner may work from the ordered coordinate list in the text alternative.
  4. Compare · 5 min. Cross-check the six points against the table: (2,10), (3,9), (4,14), (5,13), (6,16). A graph with joined lines would imply continuity not shown by six weekends.
  5. Transfer · 4 min. Ask what “visits during those hours” leaves out, including different exposure times and other weekend conditions.
  6. Exit · 2 min. Collect axis labels and one correct coordinate; reteach a reversed-axis error before Day 7.
