A lesson plan for grades K–2 Mathematics
This lesson, the fifth of a nine-part Illuminations unit titled “Amazing Attributes: Sorting and Organizing Objects,” allows students to apply knowledge of properties for sorting the buttons while working in a small group. This grouping arrangement offers students support and challenge through discussion of various options. It frees the teacher to focus on particular students and observe, interview, and document the performance of students.
