Fictional AI-style answer: “3/4 + 1/4 = 4/8.” Before reading further, draw one whole divided into four equal pieces. Shade three pieces, then the remaining piece. What total do you see?

Reviewed explanation: The pieces are still fourths, so add the numerators and keep the denominator: 3/4 + 1/4 = 4/4 = 1. Adding the denominators would change the size of the pieces.

1. Check: identify the exact error rather than trusting a confident answer.
2. Explain: use a drawing or another independent method to support the correction.
3. Transfer: test 2/3 + 1/3 yourself. The result is 3/3 = 1.

Teacher checkpoint: ask the learner to explain why the denominator stays unchanged when adding equal-sized parts. A correct answer without that explanation is a starting point for discussion, not proof of mastery. No AI account or student information is needed.

The downloadable lab expands this practice into a 15–20 minute activity. For a broader teacher-and-leader planning path, use the School AI Starter Bundle link below.
