1 approach
Scatter Graphs means practising the idea at the table with counters or paper models and one clear check. We will demo once, then your child tries.
Materials: Scatter-plot grid on paper; A short list of (x,y) pairs. 1. Say the goal of Scatter Graphs in plain words once. 2. Adult plots five points and describes the trend as positive, negative, or none. 3. Child plots three small scatter sets and names each trend. 4. Fresh check: one fresh trend description. Record and stop. Done: three scatter plots with a trend word each. Proof: parent note of examples and results. Stop: End after the fresh check; keep optional challenge for another day.

Check understanding
- Plot 10 data points on a scatter graph with correct axis labels and a consistent scale
- Draw a line of best fit by eye, ensuring roughly equal numbers of points above and below
- Use the line of best fit to estimate a y-value for a given x-value within the data range
“If your child has data comparing hours of sleep and test scores for 10 students, can they plot the points on a scatter graph, draw a line of best fit, and use it to predict a score for someone who slept 7 hours?”
