Answer: $2$ fourths. Count the shaded parts and use the share name.

Flashcard 19: What happens to the size of each share when a whole is cut into more equal shares?

Answer: Each share becomes smaller. More equal shares divide the whole into smaller pieces.

Flashcard 20: What word names each of $4$ equal shares of a whole circle or rectangle?

Answer: Fourths (quarters). When split into 4 equal parts, each part is a fourth or quarter.

Flashcard 21: If you decompose a whole into more equal shares, do the shares become larger or smaller?

Answer: Smaller. More equal shares means each share is a smaller portion.

Answer: The whole is $4$ fourths (quarters). Four fourths combine to make one complete whole.

Flashcard 23: Which option shows a circle partitioned into fourths: $4$ equal parts or $4$ different parts?

Answer: $4$ equal parts. Fourths must be equal in size, not different.

Flashcard 24: Which phrase correctly describes $\frac{1}{4}$ of a shape: "fourth of" or "half of"?

Answer: "Fourth of". Use "fourth of" to describe $\frac{1}{4}$ of something.
