Activity - Name of Activity
- Activity 1
Positive and negetive slope
Estimated Time
1 Hour
Materials/ Resources needed
Graph sheets
Prerequisites/Instructions, if any
- students should know what is slope/how to calculate if coordinates of the points on the are given
- basic operation of numbers
Multimedia resources
Website interactives/ links/ simulations/ Geogebra Applets
Process (How to do the activity)
Observe the following table and analyse the relation between X and Y (X,Y).
You will find that in one case the value of Y goes on incresing with the value of x ,but in the other case the value of Y goes on decreasing with the value of x.
In both the cases visualise the orientation of line segment.
If the value of Y decrease with the value of X the line will have negetive slope
If the value of Y increse with the value of X the line will have negetive slope
Developmental Questions (What discussion questions)
- Observe the points on the graph sheet.Build the relation betwen X and Y values
- Record your observations
