Suitable for Grades: 4th Grade
CCSS: 4.MD.C.5.A, 4.MD.C.5.B
CCSS Description: 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.
Measure angles in whole-number degrees using a protractor. Sketch angles of specified measure
This worksheet is all about calculating missing angles around a point. Students will complete sums to 360 degrees in section A. Then in section B they will use the fact that angles around a point sum to 360 degrees to find missing angles in nine different images.
