Instructions
Play through this interactive game to learn about Angles Are Measured By Number Of Degrees. Suitable for Grade 3, Grade 4, Grade 5.
Main Concepts
Understand equal partitioning and unit iteration to understand angle and turn measure.
An angle is the union of two rays, a and b, with the same initial point P. The rays can be made to coincide by rotating one to the other about P; this rotation determines the size of the angle between a and b.
In an angle each ray determines a direction and the angle size measures the change from one direction to the other.
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.
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.
An angle that turns through n/360 of a circle is called a “n-degree angle” – use multiple values for n.
A ray that moves from point A to point B one degree at a time n times has an angle measure of n degrees.
The number of one-degree angles in an angle that measures n degrees is n.
Discussion Questions
Before the Game
In this game you will be measuring angles to destroy asteroids - when might you need to measure angles in real life? What does a circle have to do with measuring angles?
After the Game
How did you manage to figure out the correct angles to steer the ship in the asteroid field? According to the game, a 180 degree angle is what fraction of a circle? Can you point out five 90 degree angles in your classroom?
