A lesson plan for grades K–1 Mathematics
In this lesson, the second of a nine-part Illuminations unit titled “Amazing Attributes: Sorting and Organizing Objects,” students have opportunities to identify properties and to sort, classify, organize, and display data. They solve problems and make, explain, and defend conjectures. They extend their knowledge by making generalizations and consolidating their thinking.
