This is a PDF download for one worksheet, but there are two versions. It is a sample page from my upcoming Mega Spring Worksheet pack :)
If you plan on having your students just use the coloring, then this activity is recommended for grades 2 and up.
Because the adding portion of this activity requires half values, the adding version of the activity would be recommended for grades 5 and up.
Version 1- Color the Note and Rest durations based on the color key.
Version 2- Add the Note and Rest durations in each petal, then write the total in the center of the flower.
