Topic_A_Foundations_for_understanding_area

Topic A includes lessons 1-4. "Understand area as an attribute of plane figures. Decompose and recompose shapes to compare areas. Model tiling with centimeter and inch unit squares as a strategy to measure area. Relate side lengths with the number of tiles on a side." EngageNY

Topic_C_Arithmetic_properties_using_area_models

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

Topic_B_Concepts_of_area_measurement

Topic B includes lessons 5-8. "Form rectangles by tiling with unit squares to make arrays. Draw rows and columns to determine the area of a rectangle given an incomplete array. Interpret area models to form rectangular arrays. Find the area of a rectangle through multiplication of the side lengths." EngageNY

Topic_D_Applications_of_area_using_side_lengths_of_figures

Topic D includes lessons 12-16. "Solve word problems involving area. Find areas by decomposing into rectangles or completing composite figures to form rectangles. Find areas by decomposing into rectangles or completing composite figures to form rectangles. Apply knowledge of area to determine areas of rooms in a given floor plan. Apply knowledge of area to determine areas of rooms in a given floor plan." EngageNY (Currently, we do not have content for Lesson 12.)
