Students will learn out how to partition a rectangle using by partitioning shapes with rows and columns.
Introduction
(5 minutes)- Display a large rectangle on the projector using a piece of paper or pre-cut rectangle.
- Say, “This is my birthday cake. I want to see how many pieces of cake I have to share. Each piece needs to be this big (hold up a square color tile). How can I figure out how many pieces of cake there are?”
- Have students turn and talk to a partner to share their ideas. Then invite a few pairs to share their thinking with the class. Ideas might include: tracing the tiles, creating columns or rows of squares, or guessing.
- Explain that today you are going to practice dividing something into equal pieces.
