## 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.

Geometric measurement: understand concepts of area and relate area to multiplication and to addition.

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).

Geometric measurement: understand concepts of angle and measure angles.

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.

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.

Measure angles in whole-number degrees using a protractor. Sketch angles of specified measure.

Recognize angle measure as additive. When an angle is decomposed into non-overlapping parts, the angle measure of the whole is the sum of the angle measures of the parts. Solve addition and subtraction problems to find unknown angles on a diagram in real world and mathematical problems, e.g., by using an equation with a symbol for the unknown angle measure.
