In this lesson, we begin to learn about arrays and the area of a rectangle with Farmer Ben. Using square units on the farm, students learn to count the square units of a partitioned rectangle to find the area. We also learn how to partition rectangles into square units. Whether counting one-by-one or skip counting, students develop a strong foundation to understand the area of shapes. Maybe we can grow some tomato plants along the way!

Understand that when given a rectangle partitioned into squares, you can count each square unit to find the total area

Understand that skip counting is a quicker way to find total area

Learn to partition a given rectangle into square units
