27. Partition circles and rectangles into two, three, or four equal shares. Describe the shares using such terms as halves, thirds, half of, or a third of, and describe the whole as two halves, three thirds, or four fourths.

a. Explain that equal shares of identical wholes need not have the same shape.

In this activity, the teacher will use the video, "Partition a Circle Into Two, Three, or Four Equal Shares," to discuss misunderstandings/misconceptions when identifying equal shares(s). The teacher will use the Google Slide presentation, "Name the Missing Equal Shares With Circles and Rectangles," to review what students know and to find the missing equal shares of circles and rectangles. The students will complete to Google Doc assignment, "This shape is Partitioned Into," to show their learning of the new concept.

This resource was created in partnership with Dothan City Schools.

27. Partition circles and rectangles into two, three, or four equal shares. Describe the shares using such terms as halves, thirds, half of, or a third of, and describe the whole as two halves, three thirds, or four fourths.

a. Explain that equal shares of identical wholes need not have the same shape.

In this activity, the teacher will begin with the video, Partition Shapes Into Equal Shares. The teacher will review the definition of partition, whole, equal shares, halves, thirds, and fourths. The teacher will use paper plates, construction paper, and card stock to demonstrate partitioning the whole into equal shares of halves, thirds, and fourths.

a. Explain that equal shares of identical wholes need not have the same shape.

In this activity, the teacher will present students with the video Partitioning Circles and Rectangles. The teacher will introduce and define the math terms whole, equal shares, partition, halves (half of), thirds (third of), and fourths (fourth of). The teacher will use the Google Slide presentation to build and activate students' background/prior knowledge of circles, and rectangles while expanding students' knowledge of the math terms.

27. Partition circles and rectangles into two, three, or four equal shares. Describe the shares using such terms as halves, thirds, half of, or a third of, and describe the whole as two halves, three thirds, or four fourths.

a. Explain that equal shares of identical wholes need not have the same shape.

Students will use paper to model the partitioning of rectangles into two, three, and four equal shares. Students will transfer this concrete model to represent equal shares on a drawing, labeling the shares as halves, thirds, or fourths. Throughout the lesson, the teacher will use an interactive geoboard app to guide instruction and represent student ideas.

This activity was created as a result of the ALEX Resource Development Summit.
