Math for first graders
Geometry Cut and Paste - Math Common Core Standards 3rd, 4th, & 5th
This is the vocabulary my students needed (but were missing) to describe the differences between quadrilaterals. The quadrilateral cut and paste activity really required students to wrestle with the definitions. The activity supports CCSS.Math.3.G.A.1 Understand that shapes in different categories may share attributes, and that the shared attributes can define a larger category. Recognize rhombuses, rectangles, and squares as examples of quadrilaterals.
