The resources above correspond to the standards listed below:

Maryland College and Career-Ready Standards

MD.MA.3.MD. Measurement and Data (MD)
3.MD.C. Geometric measurement: understand concepts of area and relate area to multiplication and to addition.
3.MD.C.6. Major Standard: Measure areas by counting unit squares (square cm, square m, square in., square ft., and improvised units).
3.MD.C.6.1. Ability to use manipulatives and visual models to calculate area.
3.MD.C.7d. Major Standard: Major Standard: Relate area to the operations of multiplication and addition – Recognize area as additive. Find areas of rectilinear figures by decomposing them into non-overlapping rectangles and adding the areas of the non-overlapping parts, applying this technique to solve real-world problems.
3.MD.C.7d.2. Knowledge that rectilinear figures refer to any polygon with all right angles.
MD.MA.3.G. Geometry (G)
3.G.A. Reason with shapes and their attributes.
3.G.A.1. Supporting Standard: Understand that shapes in different categories (e.g., rhombuses, rectangles, and others) may share attributes (e.g., having four sides), and that the shared attributes can define a larger category (e.g., quadrilaterals). Recognize rhombuses, rectangles, and squares as examples of quadrilaterals, and draw examples of quadrilaterals that do not belong to any of these subcategories.
3.G.A.1.1. Ability to compare and sort polygons based on their attributes, extending beyond the number of sides (2.G.A.1).
3.G.A.1.2. Ability to explain why two polygons are alike or why they are different based on their attributes.
