What This Standard Means
What Students Need to Do
- Students split circles and rectangles into equal shares. They identify each share as a half or a fourth and check that all shares are the same size.
What Mastery Looks Like
- A student can draw or fold a shape into equal shares and name one share correctly. The student can explain why unequal pieces are not halves or fourths.
Common Misconceptions
- Students may count two or four pieces without checking that the pieces are equal in size. They may think fourths must look like four narrow strips or confuse one fourth with four pieces.
How to Assess It
- Give each student a paper circle and rectangle. Ask them to show two equal shares on one shape, four equal shares on the other, and label each share.

Ways to Teach It
Have students fold paper circles and rectangles into halves and fourths, then cut and stack the pieces to check equality.
Show one equally divided rectangle and one unevenly divided rectangle, then ask, “Which shows fourths, and how do you know?”
Play a card sort where students match shape pictures to the labels whole, half, and fourth.
Use paper sandwiches or pizzas and ask students to plan fair shares for two people and four people.
