I used this with my first graders for exploring sol and mi patterns. As an individual assessment, each student came up to the board and created their pattern while other students were busy with something else (one heart for ta, two small hearts for ti-ti, and the Z for a rest). They sang their patterns with me! They loved the activity.
Clone the pages to meet the number of students that you have in your class so they can have their own heart to start fresh!
