The document provides an overview of a unit on rhythm. It begins by outlining the learning objectives which are to understand technical rhythm terminology, perform rhythms from notation, and create original rhythm compositions. It then defines some key rhythm concepts like beats, bars, time signatures, note values and provides examples. Learners are instructed to practice clapping rhythms, work in groups to create short rhythm pieces, and compose a longer original piece with a partner using a keyboard. The unit concludes with an assessment for learners to describe their composition and identify their current level and next steps.
