warm-up
Creates a single 3-5 minute warm-up activity (bell-ringer, do-now) that activates prior knowledge and connects to the day's learning objective.
Input
{
"objective": "Students will compare fractions with unlike denominators.",
"grade": "4",
"subject": "Math",
"minutes": 5
}
Output
{
"tool": "warm-up",
"warm_up": {
"title": "Fraction Comparison Challenge",
"instructions": "Look at the two fractions on the board: 3/8 and 1/4. Without computing, which is larger? Write your prediction and reasoning in your journal.",
"duration_minutes": 5,
"materials": ["whiteboard", "math journals"],
"connection_to_lesson": "Builds intuition for comparing fractions before formalizing with common denominators"
},
"human_review_required": true
}
Do NOT use this atom for
- Full lesson planning (use lesson-planner)
- Assessment item generation (use atom-assessment-item)
- Activities longer than 10 minutes (use atom-activity-generate)
Pipeline note
Follows references/method.md at the Generation step (warm-up creation). Output conforms to protocol-layer/metadata-schema.md. human_review_required: true — teacher should verify appropriateness for their specific class.
