Multiplication and Area

Module 4 Lessons:

Topic A: Foundations for Understanding Area

• Lesson 1: Understand area as an attribute of plane figures.
• Lesson 2: Decompose and recompose shapes to compare areas.
• Lesson 3: Model tiling with centimeter and inch unit squares as a strategy to measure area.
• Lesson 4: Relate side lengths with the number of tiles on a side.

Topic B: Concepts of Area Measurement

• Lesson 5: Form rectangles by tiling with unit squares to make arrays.
• Lesson 6: Draw rows and columns to determine the area of a rectangle given an incomplete array.
• Lesson 7: Interpret area models to form rectangular arrays.
• Lesson 8: Find the area of a rectangle through multiplication of the side lengths.

Topic C: Arithmetic Properties Using Area Models

• Lesson 9: Analyze different rectangles and reason about their area.
• Lesson 10: Apply the distributive property as a strategy to find the total area of a large rectangle by adding two products.
• Lesson 11: Demonstrate the possible whole number side lengths of rectangles with areas of 24, 36, 48, or 72 square units using the associative property.

Topic D: Applications of Area Using Side Lengths of Figures

• Lesson 12: Solve word problems involving area.
• Lesson 13: Find areas by decomposing into rectangles or completing composite figures to form rectangles.
• Lesson 14: Find area by decomposing into rectangles or completing composite figures to form rectangles.
• Lesson 15: Apply knowledge of area to determine areas of rooms in a given floor plan.
• Lesson 16: Apply knowledge of area to determine areas of rooms in a given floor plan.
