2-min Fluency Warm-up — Solid math in your head.
Faces on 2 cubes:
Vertices on 2 pyramids:
Faces on a cube + a pyramid:
Edges on a cube − edges on a pyramid:
Solids are everywhere! Write which solid each object looks like.
A basketball =
A soup can =
An ice cream cone =
A tissue box =
The Great Pyramid in Egypt =
2D and 3D shapes are related! The faces of solids are 2D shapes.
What 2D shape are the faces of a cube?
What 2D shape is the flat face of a cone?
What 2D shapes make a pyramid's faces?
What 2D shape do you see at the ends of a cylinder?
Number Talk — Explain WITHOUT counting.
A cube and a rectangular prism have the same number of faces, edges, and vertices. Why do you think that is?
My thinking:
Which would stack better in a cupboard: cans (cylinders) or balls (spheres)? Explain using faces and curves.
My thinking:
Read carefully. Then create your own!
A grocery store stacks 5 soup cans in a row. Each can has 2 circle faces (top and bottom). How many circle faces are in the whole row?
My thinking:
circle faces
Create Your Own — Go on a 3D shape hunt in your house! Find one real object for each solid and write it down.
