Standards Alignment
National Standards
CCSS.MATH.3.MD.5 -- Recognize area as an attribute of plane figures and understand concepts of area measurement.
CCSS.MATH.4.MD.3 -- Apply the area and perimeter formulas for rectangles in real world and mathematical problems. For example, find the width of a rectangular room given the area of the flooring and the length, by viewing the area formula as a multiplication equation with a• Understand measurable attributes of objects and the units, systems, and processes of measurement
o Understand such attributes as length, area, weight, volume, and size of angle and select the appropriate type of unit for measuring each attribute;
o Explore what happens to measurements of a two-dimensional shape such as its perimeter and area when the shape is changed in some way.
