Marshmallow and Pretzel Shapes

The students used marshmallows and pretzels to model 2D and 3D shapes. As they built the various shapes, we talked about the similarities and differences between them. We talked about how many edges and vertices each had. We discussed what shapes rolled, stacked, and could slide.

Pumpkin Shapes

While learning about the attributes of shapes, we discussed that the attributes stay the same no matter how large or small you make that shape. The students explored this concept by making larger squares, square rectangles, and triangles out of smaller pattern blocks. They then used paper pattern blocks to make a pumpkin shape. As they worked we discussed how many sides and vertices each shaped had.

Shape Attributes

As a part of our study of shapes, the students made shapes on geoboards. We discussed that even if shapes a different sizes, their attributes remain the same. As they made the various triangle, square, and square rectangle shapes, they counted the number of sides and vertices. They also drew pictures of their shapes on a geoboard recording sheet.

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.
