The various resources listed below are aligned to the same standard, (3MD05) taken from the CCSM (Common Core Standards For Mathematics) as the Measurement Worksheet shown above.

*Recognize area as an attribute of plane figures and understand concepts of area measurement.*

*A square with side length 1 unit, called "a unit square," is said to have "one square unit" of area, and can be used to measure area.**A plane figure which can be covered without gaps or overlaps by**n*unit squares is said to have an area of*n*square units.
