This pack includes 3 types of worksheets that encourage students to explore the various attributes of shapes. The first set involves sorting shapes using defining attributes. The second type involves counting sides or corners of various shapes. The third type asks students to list defining attributes of given shapes. These would make great additions to support your geometry unit and are aligned to the common core.
