Goals:

1. Vocabulary:

I know what a line, line segment, ray, vertex and angle are.

I know what an acute, obtuse, straight, right and reflex angle are.

2. I can draw and measure angles with a protractor. I know how to place my protractor. I place the dot at the vertex (point). I place one side of the angle on the base line of the protractor. I know which scale to read.

3. I can draw and measure reflex angles with a protractor.

4. I estimate the size of an angle to determine if my measurement is correct.
