How can we use multiplication and addition to calculate the area of rectangles, and why is this understanding important for real-world applications?
Critical Thinking: Applying mathematical operations to understand and solve area-related problems.
Responsibility: Using mathematical knowledge responsibly to make decisions in real-life scenarios.
Adaptive Perseverance: Persisting in solving complex problems involving the calculation of area.
How does tiling help us understand the concept of area in rectangles?
Why do we multiply the side lengths of a rectangle to find its area?
How can we use addition to find the area of non-rectangular shapes made up of rectangles?
Students will calculate the area of rectangles by multiplying side lengths and by tiling.
Students will demonstrate how the area of rectangles relates to multiplication and addition.
Students will use addition to find the area of non-rectangular shapes.
Standard
3.MD.C.7: Relate area to the operations of multiplication and addition. Find the area of a rectangle with whole-number side lengths by tiling it, and show that the area is the same as would be found by multiplying the side lengths.
