Adding Fractions Using Area Model

The video tutorial explains how to add fractions using the area model. It emphasizes the importance of having common denominators and demonstrates this through visual representations using rectangles. The tutorial provides examples of adding fractions like 1/4 and 2/3, and 2/5 and 2/3, by finding common denominators through the area model. The method is presented as an alternative to the standard algorithm, offering a visual and intuitive way to understand the concept of common denominators and fraction addition.

Why is it important to have common denominators when adding fractions?

• To simplify the fractions

• To be able to add the fractions directly

• To ensure the fractions are equivalent

• To make the fractions look similar

What is the first step in using the area model to add fractions?

• Drawing rectangles to represent fractions

• Converting fractions to decimals

• Finding the least common multiple

• Drawing circles to represent fractions

How do you represent 1/4 using a rectangle in the area model?

• Shade the entire rectangle

• Divide the rectangle into 4 equal parts and shade one part

• Divide the rectangle into 3 equal parts and shade two parts

• Shade half of the rectangle

What is the purpose of shading parts of the rectangle in the area model?

• To make the rectangle look complete

• To confuse the students

• To represent the fraction visually

• To make the drawing colorful

What is the first step in the area model method for adding fractions?

• Simplifying the fractions

• Converting fractions to decimals

• Drawing rectangles to represent each fraction

• Finding the least common multiple

What is the purpose of cutting the rectangles into smaller pieces in the area model?

• To change the fractions to decimals

• To simplify the fractions

• To make the drawing look complex

• To create common denominators

After creating common denominators, what is the new fraction for 1/4?

• 2/12

• 4/12

• 3/12

• 1/12

How many pieces do you get when you cut the thirds into fourths?

• 9 pieces

• 12 pieces

• 15 pieces

• 18 pieces

What is the new fraction for 2/3 after creating common denominators?

• 8/12

• 9/12

• 7/12

• 6/12

How do you know when you have achieved common denominators using the area model?

• When the numerators are equal

• When the rectangles are fully shaded

• When all pieces are the same size

• When the fractions are simplified
