This is a worksheet with a review of the lesson 11.1 in the 4th grade Go Math series: Angles and Fractional Parts of a Circle
Can be used as a quiz, formative assessment, review, extra help, or homework.
Recognize angles as geometric shapes that are formed wherever two rays share a common endpoint, and understand concepts of angle measurement: 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.
