c.Collecting of Assignments
d.Review or Reap of the previous lesson
2.Motivation
- Lay one yard stick flat on the ground. Lay another yard stick vertically against a wall.
- Have students use terms to explain, to a partner, the positions of these yard sticks.
-Have students share the terms they came up with to describe the position of the yard sticks.
-Explain that it is hard to describe slope using everyday language, but it is easy to describe with mathematics.
B. Presentation
