Fractions and Measurement Concepts

Mrs. Lamour teaches fifth graders about adding and subtracting fractions with unlike denominators. The lesson includes a warm-up exercise, a problem involving salad dressing ingredients, and two additional problems: one about walnut measurements and another about hiking distances. The video emphasizes finding common denominators and using equivalent fractions to solve problems. The lesson concludes with a cool down exercise and a summary of the strategies used.

What is the main focus of Unit 6 Lesson 12?

• Converting fractions to decimals

• Multiplying fractions

• Adding and subtracting fractions with unlike denominators

• Dividing fractions

If a fraction is close to 1, what does it imply about its numerator and denominator?

• The numerator is slightly less than the denominator

• The numerator is much smaller than the denominator

• The numerator is much larger than the denominator

• The numerator is equal to the denominator

How much olive oil does Priya need to borrow if she has 2/3 cup and needs 3/4 cup?

• 1/4 cup

• 1/3 cup

• 1/8 cup

• 1/6 cup

Why might 1 tablespoon of olive oil not be enough for Priya's recipe?

• Because 1 tablespoon is equal to 1/12 cup

• Because 1 tablespoon is smaller than 1/12 cup

• Because 1 tablespoon is not a standard measurement

• Because 1 tablespoon is larger than 1/12 cup

What is the total volume of Priya's salad dressing according to her recipe?

• 1 and 1/4 cups

• 2 cups

• 1 and 7/12 cups

• 1 and 1/2 cups

How many cups of walnuts does Jada need to add if she already has 5/6 cup and needs 1 and 1/3 cups?

• 1/6 cup

• 1/3 cup

• 1/2 cup

• 1/4 cup

What strategy is used to solve problems involving fractions with different denominators?

• Using a calculator

• Finding a common numerator

• Finding equivalent fractions with a common denominator

• Converting fractions to decimals
