understanding what is a Slope
Learning objectives
- Slope is measure of the steepness of a line.
- Students will understands that slope increases with the steepness.
- Students will recognize and make a connection between the magnitude of the slope and the steepness of a line.
- Students will understands that Slope is a number (magnitude).
- Students understands that Slope is the orientation or inclination of a line with the X-axis.
- Students should also be able to draw a line with a specific slope.
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
- Activity No #1 understanding what is Slope of a line
Positive and Negetive Slope
Learning objectives
- Students should also be able to visualise a line with positive and negetive Slope
- Students should also be able to differentiate a line with positive and negetive Slope
Notes for teachers
If the change in Y with the value of X decreases corresponding line will have Negetive Slope
If the change in Y with the value of X increases corresponding line will have Positive Slope
Activities
- Activity No 1Positive and negetive slope
