Introduction to the lesson
Let's review how to use an area model to represent a fraction .
Which of the following shows \dfrac{2}{6} of the area shaded?
For an area model to represent a fraction:
The top part of the fraction (numerator) tells us how many parts of the shape should be shaded. The bottom part of the fraction (denominator) tells us how many parts to divide the shape up into.
Let's look at representing fractions as areas of shapes.
What fraction is shown here?
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.
