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.
