Short Description
A set or resources to help students learn how to measure and estimate angles.

Long Description

In this set of resources students learn how to use a protractor to measure angles made by lines and in real life images.  Resources include 

  • Google Drawing with virtual protractor

  • Sort activity for acute, obtuse and right angles

  • Google Doc where students estimate angles in real life images

  • Google Doc and videos on How to use a Protractor

  • Printable worksheets to practice measuring angles

     

    Common Core Standards for this set or resources:

    Geometric measurement: understand concepts of angle and measure angles.

    CCSS.MATH.CONTENT.4.MD.C.5
    Recognize angles as geometric shapes that are formed wherever two rays share a common endpoint, and understand concepts of angle measurement:
    CCSS.MATH.CONTENT.4.MD.C.5.A
    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.
    CCSS.MATH.CONTENT.4.MD.C.5.B
    An angle that turns through n one-degree angles is said to have an angle measure of n degrees.
    CCSS.MATH.CONTENT.4.MD.C.6
    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.
