This document provides a teaching guide for a Grade 1 music class focusing on dynamics and tempo. It includes lesson plans, activities, and assessments for two 40-minute classes on dynamics and two 30-minute classes on tempo. The lessons introduce key concepts like loudness vs softness and fast vs slow through songs, games, movement, and discussion. Students demonstrate their understanding by performing songs at different volumes and speeds, creating poems using loud and soft words, and identifying dynamics and tempos in various sounds and activities. The goal is for students to understand how to apply these musical elements appropriately based on the mood or style of different pieces.
