Topic 1 Factors and Area
This topic integrates numeric concepts like the Distributive Property with the
geometric concept of area. Students use their flexibility with decomposing shapes to decompose numbers into factors and to apply the Distributive Property to compute products efficiently. From their knowledge of rectangles and area, students also develop the formula for the area of parallelograms, triangles, trapezoids, and composite fi gures. Finally, students use their knowledge of factors to determine greatest common factors and least common multiples of numbers.
