This Problem Set is a part of the Lesson 11, Unit 8, Grade 2. In this lesson, students continue to explore the concept that equal parts of a rectangle can have different shapes. Using geoboards, students might partition a given rectangle into two squares, two rectangles, or even two triangles. In addition, students partition a square paper into differently shaped fourths and explain how one of the fourths (the square shape) can be transformed into the other fourth (the rectangle shape).
