Which known creature is most like your new one? Change one feature.
Make a creature that belongs near a boundary. Ask a partner which feature changed its neighbours.
Find the closest teaching example using weighted squared distance. Ties use the first supplied example.
Cut these cards apart. Use the original example first, then let a partner supply a changed case. Keep sealed/final cards with the teacher until the learner commits a rule.
