1. What are edges?
- the lines where two faces meet
- the flat surfaces of shapes
- the corners of shapes
Great job! Edges are the lines where two faces meet in 3-D shapes.
Sorry, that is not correct. Edges are the lines where two faces meet in 3-D shapes.
Sorry, that is not correct. Edges are the lines where two faces meet in 3-D shapes.
2. What are faces?
- the corners of shapes
- the lines where two faces meet
- the flat surfaces of shapes
Sorry, that is not right. Faces are the flat surfaces of shapes.
Sorry, that is not right. Faces are the flat surfaces of shapes.
Way to go! Faces are the flat surfaces of shapes.
3. Which of the following shapes is a cone?
Sorry, that is incorrect. A cone has 1 vertex, 1 face, and no edges. Think of an ice cream cone.
Yes! That shape is a cone because it has 1 vertex, 1 face, and 1 edge.
Sorry, that is incorrect. A cone has 1 vertex, 1 face, and no edges. Think of an ice cream cone.
4. How many faces does a rectangular prism have?
- 12
- 8
- 6
Sorry, that is not correct. A rectangular prism has 6 faces, or flat surfaces.
Sorry, that is not correct. A rectangular prism has 6 faces, or flat surfaces.
Great! A rectangular prism has 6 flat surfaces called faces.
5. How many edges does a sphere have?
- 0
- 1
- 2
Nice job! A sphere has 0 edges because it is round.
Sorry, that is not right. A sphere has 0 edges because it is round.
Sorry, that is not right. A sphere has 0 edges because it is round.
6. Which shape is this?
- triangular prism
- cone
- cube
Sorry, that was incorrect. This is a cube because all 6 of the faces are in the shape of squares.
Sorry, that was incorrect. This is a cube because all 6 of the faces are in the shape of squares.
YYes! This is a cube because it has 6 square faces, 12 edges, and 8 vertices.
7. How many vertices does a triangular prism have?
- 5
- 6
- 9
Sorry, that is not right. A triangular prism has 6 vertices, or corners.
Wonderful! A triangular prism has 6 vertices.
Sorry, that is not right. A triangular prism has 6 vertices, or corners.
8. What do a sphere, cylinder, and cone have in common?
- They all have 0 vertices.
- They all have 0 faces.
- They all have 0 edges.
- They all have nothing in common.
Sorry, that is incorrect. These 3-D shapes have a different number of vertices, edges, and faces.
Sorry, that is incorrect. These 3-D shapes have a different number of vertices, edges, and faces.
Sorry, that is incorrect. These 3-D shapes have a different number of vertices, edges, and faces.
Great! These 3-D shapes have a different number of vertices, edges, and faces.
9. Which of the following sets of attributes describes a cylinder?
- 3 faces, 0 edges, 0 vertices
- 2 faces, 2 edges, 0 vertices
- 3 faces, 2, edges, 0 vertices
Sorry, that is not right. A cylinder has 2 faces in the shape of circles, 0 edges and 0 vertices.
Nice! A cylinder has 2 faces, 0 edges, and 0 vertices!
Sorry, that is not right. A cylinder has 2 faces in the shape of circles, 0 edges and 0 vertices.
