Add Mixed Numbers Using Properties of Operations

This video tutorial teaches how to use area models to add mixed numbers by applying the properties of operations. It explains the components of mixed numbers, how to convert them into equivalent fractions, and common mistakes to avoid. The tutorial demonstrates adding mixed numbers by first adding whole numbers and then fractions, using area models to verify results. The lesson concludes with a final example to reinforce the concepts.

What is a mixed number composed of?

• A fraction and a decimal
