Which standards are students learning in this unit? M4.C.3.1.1 -- Match or plot the ordered pair with the appropriate point (or object) on a simple grid 4.MD.5a -- Important 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. 4.MD.5b -- Important An angle that turns through n one-degree angles is said to have an angle measure of n degrees. 4.MD.6 -- Important Measure angles in whole-number degrees using a protractor. Sketch angles of specified measure. 4.MD.7 -- Important 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.
