Standards with the same topic and subject but for other grades
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.
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.
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).
Find the area of a rectangle with whole-number side lengths by tiling it, and show that the area is the same as would be found by multiplying the side lengths.
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.
Measurement & Data: Geometric measurement: Understand concepts of angle and measure angles.
An angle that turns through 𝑛 one-degree angles is said to have an angle measure of 𝑛 degrees.
