Lesson Narrative
In previous lessons, students partitioned circles and rectangles into two and four equal pieces. They learned the terms “halves” and “fourths” to describe how the shapes were partitioned. In this lesson, students describe one piece as “half of,” “a fourth of,” or “a quarter of” a whole shape. Students also learn that they can describe the whole shape as "two halves” or "four fourths.”
