Content:Identify object in our environment that are three dimensional shapes
Â
Examples of cubes

Â
Examples of cuboids
Â
Identify the flat faces,edges and vertices(corners)of cubes and cuboids

Â
Features of cubes and cuboids
Â
Â

Three dimensional shapes are cubes,cuboids,cylinders and spheres
Examples of cubes are cubes of sugar,cubes of maggi and ludo dice
Examples of cuboids are mathematical set,toothpaste box,match box,e.t.c
Â

The edges of a cube or cuboids is where the flat faces meet.The vertices is where the edge of cubes and cuboids meets.
Â
Features of cubes and cuboids
Cube

It has 6 flat faces
It has 12 edges
It has a vertices(corners)
It has a square face

Â
Cuboids
It has 6 flat faces
It has 12 edges
It has 8 vertices
It has a rectangular face
Â
Example
Take a cube of sugar and matchbox
Count the number of flat faces both objects have?

How many flat faces do the objects have?
The cube of sugar and matchbox both have 6 flat faces.
Â
Count the number of edges of cube of sugar and match box
