The video tutorial explains how to use area models to add fractions. It starts with adding fractions with the same denominator by shading parts of identical figures. Then, it covers adding fractions with different denominators by adjusting the models to have the same number of parts. The tutorial concludes with a summary of the method using visual models.

How do you represent the fraction 1/4 using an area model?

• Shade three parts of a figure divided into four equal parts.

• Shade one part of a figure divided into two equal parts.

• Shade two parts of a figure divided into four equal parts.

• Shade one part of a figure divided into four equal parts.

What is the result of adding 1/4 and 2/4 using area models?

• 2/4

• 1/4

• 3/4

• 1/2

Why can't you directly add fractions with different denominators using area models?

• The models are not drawn to scale.

• The models have different colors.

• The models are not divided into the same number of equal parts.

• The models are not the same size.

What is the first step in adjusting area models to add fractions with different denominators?

• Change the color of the shaded parts.

• Erase the existing models and start over.

• Draw a new model with more parts.

• Split one or both models to have the same number of equal parts.

After adjusting the models, what is the sum of 1/2 and 1/4 using area models?

• 1

• 1/2

• 3/4

• 1/4
