## 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.
6. 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

1. Activity No #1 understanding what is Slope of a line

## Positive and Negetive Slope

### Learning objectives

1. Students should also be able to visualise a line with positive and negetive Slope
2. 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

1. Activity No 1Positive and negetive slope
