Subtracting Mixed Fractions Using an Area Model

This video tutorial teaches how to subtract mixed and improper fractions using area models. It begins with an introduction to mixed fractions and explains how each part of a fraction provides specific information. The tutorial highlights common mistakes, such as misinterpreting mixed fractions. It then provides examples of subtracting mixed fractions (2 1/2 - 1 1/2) and improper fractions (20/3 - 13/3) using area models, demonstrating the process step-by-step. The lesson concludes with a summary of the subtraction process using area models.

What does the denominator in a fraction tell us when using an area model?

• The number of parts to subtract

• The number of whole parts to shade

• The total number of parts in the numerator

• The number of equal parts to divide the area model into
