Teachers should allow ChatGPT with purpose and guardrails. Use it for brainstorming, reading support, feedback, and study help, not to produce final drafts. Start with teacher-led demos in K to 2, guided small-group use in grades 3 to 5, limited independent use with checks in grades 6 to 8, and accountable independent use in grades 9 to 12 and college. Keep equity, privacy, and visible thinking at the center.
