Comparing Fractions Strategies for 3rd Graders

The video by Yvonne from Kiwi Math covers three strategies for comparing fractions, focusing on third-grade concepts. The first strategy, common denominators, involves comparing fractions with the same denominator by examining the numerators. The second strategy, common numerators, compares fractions with the same numerator by analyzing the denominators. The final strategy, the missing piece method, involves comparing fractions by identifying which fraction is closer to a whole. These strategies are foundational for fourth-grade math and help students understand fraction sizes and comparisons.

What does the denominator tell us in a fraction?

• The number of pieces we are looking at

• The color of the pieces

• The size of each piece

• The total number of pieces possible

If two fractions have the same denominator, how do we determine which one is greater?

• By comparing the numerators

• By adding the denominators

• By subtracting the numerators

• By dividing the denominators

In the context of fractions, what does the numerator indicate?

• The color of the pieces

• The total number of pieces

• The size of the whole

• The number of pieces being considered

What does having the same numerator in two fractions imply?

• The size of the pieces is the same

• The denominators are irrelevant

• The number of pieces is the same

• Both fractions are equal

If two fractions have the same number of pieces, how do we find out which fraction is greater?

• By comparing the sizes of the pieces

• By adding the numerators

• By comparing the denominators

• By multiplying the numerators

Why is a piece of 1/6 larger than a piece of 1/8?

• Because the whole is divided into more pieces

• Because the whole is divided into fewer pieces

• Because 1/6 is a more common fraction

• Because 6 is greater than 8

Why is a fraction with a smaller denominator considered to have larger piece sizes?

• Because it has fewer pieces overall

• Because it has a larger numerator

• Because each piece represents a larger portion of the whole

• Because it is a more complex fraction

What does the missing piece strategy help us understand?

• How many pieces are in a whole

• The size of the whole

• Which fraction is closer to being a whole

• The color of the missing piece

How can we tell which fraction is greater when comparing fractions with a missing piece?

• By finding which has more pieces

• By determining which is missing a larger piece

• By adding the pieces together

• By subtracting the pieces from the whole

If a fraction is missing a smaller piece to become a whole, what does it imply?

• It cannot be compared without additional information

• It is equal to the fraction missing a larger piece

• It is greater than the fraction missing a larger piece

• It is less than the fraction missing a larger piece
