• Estimating angle measures using 45 degrees, 90 degrees, 180 degrees 270 degrees, or 365 degrees as referents
• Measuring angles

Triangles:
As a group activity, the students will use Power Point Presentation slides to identify the different types of triangles.

Angles
The students will determine the number of degrees for each angle of each pattern block by using the right angle of the square as a reference.

Making Angle Finders from Index Cards
Students will use an index card to identify: straight, right, acute and obtuse angles

Angles by Chonna Parker
Students will be able to define and draw angles

The Three Types of Angles
Students will identify the three types of angles.
