Activity - Name of Activity

  1. Activity 1
    Positive and negetive slope

Estimated Time

1 Hour

Materials/ Resources needed

Graph sheets

Prerequisites/Instructions, if any

  1. students should know what is slope/how to calculate if coordinates of the points on the are given
  2. 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

[This Geogebra applet helps in visualising Positive and negetive Slope]

Developmental Questions (What discussion questions)

  1. Observe the points on the graph sheet.Build the relation betwen X and Y values
  2. Record your observations
