Shape Attributes

The students have recently been learning about the various attributes of shapes. They worked on various lessons including sorting shapes into 2D and 3D shapes. They also identified the number of edges, vertices, and faces of 3D shapes using garage sale dot stickers (it helps them identify which they've already counted). Additionally, they sorted cards of various 2D and 3D shapes into categories such as rolls, has 3 or more faces, has vertices, etc. They also made various 3D shapes out of playdough.

Attributes of 2D Shapes

As we learned about the attributes of 2D shapes the students worked in cooperative groups to show examples and non-examples of circles, triangles, squares, and square rectangles. When sorting they had to verbally justify how they knew what were examples and what were non-examples by explaining the specific shape's attributes such as how many sides and vertices the shape has. The students then went on "gallery walks" to see how their classmates had sorted their shapes.
