Step 2: Teach Lesson

Triangles and Quadrilaterals have identifying attributes.

Review: Have the student sketch an example for each:

1. two parallel lines

2. two perpendicular lines

3. an acute angle

4. an obtuse angle

5. a ray

6. a line segment

7. the diameter of a circle

Activity

The student can now begin their vocabulary sorting activity. Discuss with the student the categories they chose for their vocabulary

sorts. Review basic vocabulary by having the student discuss and complete the Two-dimensional Geometry Words Foldable for their

journals. As they fill in each word, have the student show what they have sketched and written. Discuss with the student to make

sure they included vocabulary for all essential attributes and parts.
