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.
