11Finding the Missing Blocks Unit

Math VoCabulary cube: a solid figure with 6 square faces

face: the side of a solid figure edge: the line where 2 faces meet
vertex: the point where 3 or more edges meet

2 Use the solid figures to complete the table. 2. Have students find the number of faces,
edges, and vertices in solid figures. If students
Solid Figure Faces Edges Vertices have a difficult time finding the number of
a faces, edges, and vertices, have them use
8 soft geometric solids.
6 12
3. Have students find a figure that fits the
Cube description provided.
b

585

Pyramid
c

6 12 8

Rectangular
Prism

3 Who am I? Circle the figure that matches the description.

a I have 5 faces and 5 vertices. b I can roll. I look like a circle
If you look at me from the top, from the top and a triangle
from the side.
I look like a square.
