The lesson plan aims to teach 4-year-old beginner students parts of the face and body. It will use a song, video, and craft activity to help students recognize, identify, and learn the vocabulary for parts of the face like eyes, nose, mouth, and ears. It will also teach parts of the body like head, shoulders, knees and toes through singing, dancing, and miming along to the song. The lesson is organized into stages including a warm-up with the face song, presenting the new body song and vocabulary through a video, and an activity where students create faces using shapes to demonstrate their understanding.
