Are you ready?

You may have already looked at representing fractions as fractions bars or points on the number line. 

Can you answer this question?

Here is a fraction bar.

   

  1. This fraction bar has $\editable{}$ equal parts.

  2. Each part is $\frac{\editable{}}{\editable{}}$​ of the whole.

 

Learn

With any model of a fraction, we use:

  • the denominator (the bottom number of the fraction) to decide how many pieces to divide it into, and
  • the numerator (the top number of the fraction) to shade the number of pieces.

Let's learn about fractions as areas of shapes. 

 

Apply

Which of the following shows $\frac{2}{6}$26​ of the area shaded?

  1. A

    B

 

Remember!
  • The numerator (top number) is the number of parts shaded to represent the fraction.
  • The denominator (bottom number) is the number of equal parts the shape is divided into.
