Teaching Outlines

Concept 1

understanding what is a Slope

Learning objectives

1. Slope is measure of the steepness of a line.
2. Students will understands that slope increases with the steepness.
3. Students will recognize and make a connection between the magnitude of the slope and the steepness of a line.
4. Students will understands that Slope is a number (magnitude).
5. Students understands that Slope is the orientation or inclination of a line with the X-axis.

Notes for teachers

Slope is a number which represents the steepness of a line Students can relate the slope of line to the tangent of the angle of elevation.

Activities

1. Activity No1
   understanding What is a slope?

Procedure
Ask the students to observe the given table describe the pattern using words .
Ask them to plot and join the points on grids and ask how the line segments is visible in the graph.
ask them to write the relation between X and Y.
(we can come to a conclusion that the larger the absolute value of the number,the linebecomes steeper.)

X	Y

7	2
8	3
9	4

X	Y
4	1
5	3
6	5

X	Y
6	1
7	4
8	7

Assessment Questions

1. Write the relation between X and Y(as an equation)
2. plot the other points following the same pattern and join the points
3. How do we differentiate these lines from one another?from the inclination with the x-axis i.e bending of line towards x-axis
4. Can we visualise the angle so formed by the line with the X-axis?
5. What is the relation between the bending of line and angle formed by it with the X-axis?
   

We can conclude that bending(orientation of line)increases with the increse in the angle or we can say line becomes steeper with the angle of inclination.
The slope of a line is a number that measures its "steepness" It is the change in y for a unit change in x along the line.

1. How do we measure the steepness of line?
