Small clues, smaller crowds

One clue fits many make-believe people. What happens when clues join?

Make your own investigation

Invent six fictional character cards. Find two harmless-looking clues that together identify one card.

Intersect the two sets of matching cards. Compare each clue alone with their combination.

Case cards

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.

What this cannot establish

These are fictional cards; do not enter information about classmates.
