Explain that the body works like a team. Bones give support, muscles help move bones, and joints let us bend. Briefly point to your arm, elbow, and hand as examples.

Student Actions

Listen, watch, and repeat key words.

Answer orally and connect body parts to their jobs.

Wrap-Up3 minutes
Teacher Actions

Review the main ideas: bones support, muscles move, joints bend, heart pumps blood, lungs help breathing.

Student Actions

Repeat or say one fact they learned.

Support

  • Use gestures and point to your own body while explaining.

  • Listen for correct use of vocabulary during discussion.
  • Ask students to point to a joint on their body.
  • Have students explain one body part job in a sentence.
