In this lesson we will identify and describe three-dimensional shapes according to the number of faces, edges, and vertices.

Start the lesson by describing the cube(bring a real object to work on

- All the faces of the cube are squares and the same size.

- Count the sides of the cubes.- The children should count 6 sides.

- Face : the cube has 6 faces

- Edge: 12 edges where two

faces meet

- Vertex : 8 vertices where two

edges meet

rectangular prism

- Two faces of the cube are squares and 4 faces are rectangular.

- Count the sides of the rectangular prism.- The children should count 6 sides.

In order to solve this page Remind children the dashed

lines also need to be counted as edges, and the place

where these lines meet also needs to be counted as a

vertex.

Exercise 5

In this exercise children must determine what type of solid

was traced just by viewing the faces.
