What to say
“The rule is about the cards or objects—not anyone’s body, clothes, identity, or worth. Make a theory, test it, and be willing to change your mind.”

Keep it comfortable and useful.
Make room for everyone
- Read every card aloud and use large print.
- Let students submit theories verbally, in writing, or through a partner.
- Use concrete objects before abstract word patterns when helpful.
Watch out for
- Never sort students by visible or personal characteristics.
- Choose rules with enough evidence to be solvable rather than arbitrary.
