Average distance from the mean 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: Two overlapping circles drawn on paper; Counter tokens or number cards. 1. Say the goal of Average distance from the mean in plain words once. 2. Adult sorts numbers into A, B, both, or neither for “even” and “multiple of 3”. 3. Child sorts three sets into a Venn diagram and counts each region. 4. Fresh check: one fresh item placement in the overlap. Record and stop. Done: three correctly sorted Venn diagrams with region counts. Proof: parent note of examples and results. Stop: End after the fresh check; keep optional challenge for another day.
