- 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
1Relate the motivational activities conducted to the topic to be discussed.
2.Introduce the topic on Slope of the Line through Power Point Presentation.
3.Ask one student to read the definition of slope.
4.Elaborate the definition and present the formula.
5.Point out the important details and rules about the topic.
6.Give some examples and ask volunteers from the class to solve the exercises.
7.Give a generalization.
IV. Assessment
Direction: Answer the following items. Write your answers on a graphing paper.

1.(-2, 7); (4, -3)
2.(1, 2); (8, 5)
3.(8, -2); (3, -2)
B.Find the slope of each line.
1.2x + y = 6
2.3x – 4y = 12
3.x = -6
4.y + 5 = 0

2. Graph the following line with the given equation and then find its slope based on the graph you will sketch.
Modern ways of teaching is very effective now a days. Blogging is only one of those ways a teacher can introduce to his/her students. There a plenty of advantages of blogging as a teaching tool. Through "blog" students, in particular, can log on anytime and anywhere. It takes teaching and learning to a level that is beyond their classroom setting. If they have questions, they can automatically surf in the in the Internet or post it on their blog site. For teachers, they can have plenty of information and learning resources to offer to their students. Using it as tool for teaching, teachers will focus more on students discovery rather than on content delivery. Students will have a direct learning by asking and responding to "blog". Another advantage of blogging in teaching Math is that word problems may be solved on new ways and creative solutions, with the aid of "blog". Students centered learning will be more self-directed. However,despite of those advantages I mentioned above has of course an opposite. If teacher's will put too much dependency on blogging that would also create a disadvantages. Yes, pictures and videos may aid the presentation but it is still the discussion and self-directed learning that will provide benefits outside the traditional classroom learning situation.
