[i]Understand concepts of area and relate area to multiplication and to addition.[/i]
Recognize area as an attribute of plane figures and understand concepts of area measurement.
[list]
[*]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.
