The Rhythm Speller Book 4 reinforces rhythm skills based on the concepts introduced in the Music Lesson Book 4. Each page of the Rhythm Speller Book has two activities---a rhythm-writing activity and a rhythm-reading activity. The written activities reinforce note values and counting through coloring, circling, drawing, or matching. The rhythm-reading activities help students practice clapping or tapping rhythm patterns while counting aloud, playing rhythms on rhythm instruments or keys on the keyboard, and chanting words based on rhythm patterns.
