Instructions

Play through this interactive game to learn about Measure Angles Using A Protractor. Suitable for Grade 3, Grade 4, Grade 5.

Main Concepts

An angle that turns through 1/360 of a circle is called a “one-degree angle,” and degrees are the unit used to measure angles.

Angles are measured with reference to a circle with its center at the common endpoint of the rays and the rays intersection points in relation to their fraction of the circular arc.

In an angle each ray determines a direction and the angle size measures the change from one direction to the other.

Identify which angle is constructed to show a given angle measure.

When measuring an angle the center point should align with the center point of the protractor, and one arm or ray should align with the base of the protractor. The other arm will determine the angle measure in relation to the first ray.

Measure angles using a protractor.

Using a protractor accurately sketch an angle with a given angle measurement.

When sketching an angle draw a ray, align the protractor with the endpoint of the ray and make a mark at the desired angle length. Use the ruler side of the protractor to sketch a line connecting the endpoint of the first ray and the mark made for the desired angle measurement. Sketch the line to form a vertex.

Discussion Questions

Before the Game

Do all triangles have the same angles? In this game you will need to accurately read a protractor - how do you read a protractor? In this game you will use a circle protractor - what is the relationship between a circle and angles? How many right angles can be created inside of a circle? What does a 360 degree, 180 degree, and 90 degree turn look like?

After the Game

How do you use a protractor? What is the difference between an acute, obtuse, and right angle? If you did not have a protractor how could you determine the size of an angle? How do you know if you are to use the inner numbers or outer numbers on a protractor? In this game you defined angles - what is the difference between a reflex angle and an obtuse angle?
