A lesson plan for grades K–2 Mathematics
This lesson, the third of a nine-part Illuminations unit titled “Amazing Attributes: Sorting and Organizing Objects,” focuses on the observation of properties and the classification of objects to build ideas about variables. Students compare objects to identify similarities and differences. The teacher monitors the learning growth of students to determine the next steps.
