Sorting and odd one out
Strategy card
Every group has a rule that fits all its members.
- Step 1: Name what all the group members share.
- Step 2: Make the rule exact (not just "animals", but "animals that fly").
- Step 3: Test each choice against the rule.
- Step 4: Pick the one that fits every part of the rule.
Tip: If more than one answer fits, your rule is too loose. Tighten it.
Worked example
Which word does NOT belong with the others?
- A: desk
- B: worry (the answer)
- C: table
- D: shelf
Why: The other words are all furniture. “worry” is not.
