2.7B 2-2D and 2-3D figures and how they are alike and different

2.7  the student uses attributes to identify 2 and 3 dimensional geometric figures.  The student compares and contrasts 2 and 2 dimensional geometric figures or both
1	2	3
1.6a  describe and identify 2D geo figures, including circles, triangles, rectangles, and squares (a special type of rectangle) 1.6b  describe and identify 3D geo figures, including spheres, rectangular prisms (including cubes), cylinders and cones	2.7b  use attributes to describe how 2-2D figures or 2-3D figures are alike or different	3.8  the student uses formal geometric vocabulary.  The student is expected to identify, classify, and describe 2D figures, 3D figures, or both by their attributes.
use attributes to describe how 2-2D figures or 3-2D figures are alike or different                                                   use—to employ for some purpose; put into service; make use of describe—to give an account of in words; to tell in words what something or someone is like

Activities:

• Use a double bubble map to compare 2-2D or 2-3D figures
• Model using correct vocabulary (face, edge, vertices, sides, base) when comparing and contrasting
• Use manipulateives to physically touch the attributes while comparing

good math writing activity to use with 2D and 3D shapes
