| + | === Estimated Time === |
| + | 80 minutes |
| + | |
| + | Refreshment activity related to language - 15 minutes |
| + | |
| + | Introduction to Geogebra - 15 minutes |
| + | |
| + | Hands-on Activities in Geogebra on points, lines and segments with demonstration - 30 - 40 minutes |
| + | |
| + | 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. |
| + | * Non-digital : Worksheet and pencil. |
| + | |
| + | === Process (How to do the activity) === |
| + | '''Teachers work:''' |
| + | |
| + | To demonstrate - |
| + | # How to on/off computer ? |
| + | # How to open Geogebra application ? |
| + | # How to use tools in Geogebra interface? |
| + | # How to create and Save a file in Geogebra ? |
| + | # How to plot and label 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 |
| + | |
| + | === Developmental questions of the activity === |
| + | # Why we use points? What does 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? |
| + | # Give examples for points, rays, segments and lines in our day-to-day life. |
| + | # How to represent line segments, rays and lines symbolically? |
| + | |
| + | === '''Refreshment activity :''' === |
| + | <u>Guess the word</u> : |
| + | # Grouping the students(Each group has maximum 3 students) |
| + | # One student from each group pickup the word, and give 3 clues in a word to describe the vocabulary word that needs to be guessed by other group members |
| + | # The word to be guessed should not be told by the participant to other group members. |
