Multiplying Fractions with Area Models

The video tutorial explains how to multiply fractions using an area model. It begins with an introduction to the parts of a fraction, including the numerator and denominator. The teacher demonstrates the multiplication of fractions using two examples: 2/3 x 1/2 and 3/5 x 2/3. The process involves creating rows and columns based on the denominators and shading areas according to the numerators. The tutorial also covers simplifying the results using the greatest common factor.

What does the numerator of a fraction tell us?

• Number of unshaded parts

• Number of shaded parts

• Total number of rows in an area model

• Total number of parts in the whole
