The lesson plan is for a music class and focuses on teaching students about beats grouped in 2s, 3s, and 4s. Students will clap, tap, chant, walk and play instruments to demonstrate their understanding of different rhythmic patterns. They will analyze songs like "Soldier's March" and "Bahay Kubo" to identify how the beats are grouped and choose appropriate movements to match each song. The goal is for students to be able to recognize rhythmic patterns and translate them into physical movements.
