Representing Fractions on Number Line
Representing fractions on number line shows the intervals between two integers which will help us to increase the basic concept on formation of fractional numbers.
1. Represent the fractions: 2/5, 11/5, -8/5 and -3/5 on a number line.
Since, the denominator of each given fraction is 5; divide the space between every pair of two consecutive integers (on the number line) in 5 equal parts. Each part so obtained will represent the fraction 1/5 and the number line obtained will be of the form:
Representing Fractions on Number Line
To mark 2/5; move two parts on the right-side of zero.
To mark 11/5; move eleven parts on the right-side of zero.
To mark -8/5; move eight parts on the left-side of zero.
To mark -3/5; move three parts on the left-side of zero.
Answer:
vertices, edges and faces!
Vertices are the pointy bits or the corners where edges meet.
Edges are the lines around a shape.
Faces are the sides that you touch when you hold a shape.

Take a look at this gift box:
gift box
It's made up of 6 square faces.
If you fold the faces and glue them together, it becomes a cube with 8 vertices and 12 edges!

Here's a rectangular shaped gift box:
gift box
It's made up of 6 rectangular faces.
When you join the sides together, it becomes a rectangular prism with 8 vertices and 12 edges!

Here's a triangular shaped gift box:
gift box
It's made up of 5 faces (2 are triangles, 3 are rectangles).
When you join the sides together, it becomes a triangular prism with 6 vertices and 9 edges!

Here's another triangular gift box:

It's made up of 5 faces (4 are triangles, 1 is a square).
When you join the faces together, it becomes a square based pyramid with 5 vertices and 8 edges!

Here's a round gift box:
round gift box
It has 2 circular faces and 1 surface.
The surface doesn't count as a face. Faces are flat.
When you wrap the surface around the circles, it becomes a cylinder with 2 edges and 0 vertices.
There are no sharp, pointy bits in a cylinder!

You can put lots of things inside these different shaped gift boxes!
What about cones?
Take a look at this party hat:
party hat
It's made up of 1 surface and 1 circular face.
When you wrap the surface around the circle it becomes a cone with 1 vertex and 1 edge.

What about Spheres?
Spheres are really difficult to make. They have 0 faces, 0 edges and 0 vertices, which means you can't join anything together. Why not wrap up some sphere-shaped chocolates instead?

Try using what you've learned about vertices, edges and faces to make your own gift boxes and party hats!
