In this 60-minute music lesson for 5th graders, students will explore the concept of harmony through singing and collaborative activities. The lesson begins with an engaging discussion about harmony in music, followed by vocal warm-up exercises to enhance their listening and singing skills. Students will learn a two-part song, first practicing the melody and harmony separately before coming together to perform as a unified group. Later, they will work in small groups to create their own simple harmonies for familiar tunes, encouraging creativity and teamwork. The session concludes with performances of their compositions and a discussion on the importance of collaboration in music. Participation, ability to sing their assigned parts, and creativity in the group activity will serve as assessment criteria. Adaptations will be made to support all learners, ensuring a comprehensive and inclusive music experience.
