How can we extend our knowledge of halves, thirds, and fourths to new shapes? Join Mr. Waldorf as he guides students’ understanding of partitioning shapes from the previous lesson to rectangles and circles. For this lesson, you’ll need the lesson template, an object to trace a circle (such as a cup or a can), and scissors. You will also need paper and pencil. If you have access to a workbook, or a printer, we also suggest using the Lesson 10 Problem Set available using the link below the video.
