How to Use a Protractor: 8 Steps (with Pictures) - wikiHow
The paper protractor makes it quite clear how a protractor fits unit angles into the angle for measurement. Students can estimate halves, thirds, or fourths of a “wedge,” a possible name for this informal unit. Figure 8.7 illustrates how a tagboard semicircle can be made into a protractor to measure angles in wedges.

Ask leading questions to assess student understanding of what an angle is, the types of angles, estimating the measure of an angle, and the use of the protractor to draw and measure angles. Now let’s examine some angle pairs. If the sum of the measures of two angles is 90º, then the angles are complementary angles.

Task 6: Students should then measure the angles using the protractor and compare the exact answer to what they guessed. Task 7: Class discussion is conducted to see what the students have discovered about a straight angle. Students may get confused with the use of the term “Straight angle” and resort back to calling it a straight line.

They will also choose 4 of the labeled angles to measure with a protractor. Struggling learners will order number cards from 10° to 170° and order pictures of the same angles from least to greatest, matching the picture with the number of degrees. They will also practice using the protractor to make sure each angle matches the given measurement.
