Worksheet distribution - 5 minutes
Prerequisites/Instructions, prior preparations, if any
Prior understanding of Edges, corners and shapes
Materials/ Resources needed
- Digital : Computer, geogebra application, projector.

Process (How to do the activity
Teachers work:
Demonstration of
- How to create PDL in computer
- How to open Geogebra application
- Explain about Geogebra interface
- How to create and Save file in geogebra
- How to plot points, draw line segments, draw line, draw rays
Students work:
1. Plot 10 points and Name it as A, B, C, D, E, F, G, H, I, J.
2. Draw 5 line segments - AB, BD, DE, FG, AH
3. Draw 5 lines - BC, EF, AE, DG, GI
4. Draw 5 rays - OB, FD, KL, BE, RC
Create PDL with their Names and save all files in it.
Evaluation at the end of the activity
- Why we use points? What is point indicate?
- Are all points are in the same place?
- Do you think you can draw a complete picture of a line? Why?
- Can you measure the line?
- A minimum of how many points are required to fix a line.
- How many points can be plotted on a line?
- How many segments can be on a line?
