Recognize area as an attribute of plane figures and understand concepts of area measurement.
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.
An angle that turns through 𝑛 one-degree angles is said to have an angle measure of 𝑛 degrees.
Measurement & Data: Geometric measurement: Use concepts of area and relate area to multiplication and to addition.
Use concepts of area and relate area to the operations of multiplication and addition.
Measure areas by counting unit squares (square cm, square m, square in, square ft, and improvised units).
Multiply side lengths to find areas of rectangles with whole-number side lengths in the context of solving real-world and mathematical problems, and represent whole-number products as rectangular areas in mathematical reasoning.
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.
Measurement & Data: Geometric measurement: Understand concepts of angle and measure angles.
An angle is measured with reference to a circle with its center at the common endpoint of the rays, by considering the fraction of the circular arc between the points where the two rays intersect the circle. An angle that turns through 1/360 of a circle is called a “one-degree angle,” and can be used to measure angles.
