Description of activity with detailed steps

Teacher led activity

After introducing you to how to open the Geogebra file, your teacher will demonstrate two pictures sketched using Geogebra.

Watch and observe the various functionalities she uses. This will include the following:

  1. Using the different geometric shapes visible on the tool bar
  2. Defining the drawn objects as a shape (or a polygon)
  3. Rotating and moving objects
  4. Showing and making invisible the labels of points
  5. Formatting objects drawn

Student activities

  1. Create the following free sketches (or any other sketch of your choice) with Geogebra and save the images as well as the file
    1. Tree
    2. House
    3. Car
    4. Suitcase
    5. Well
  2. Draw the following given sketches using Geogebra. With a set of 3,4,5,6,7,8 segments try to draw various polygons. And define the polygons drawn as an object. After drawing the polygons, move the vertices and rotate the polygons. Is it possible to change the vertices? Observe what changes in the polygon.
  3. Look at the following images and try to create these using Geogebra.

Create multiple images using tool bar

Create multiple images and arrange them

Portfolio

  1. Your library of Geogebra files
  2. Your screenshot images of sketches created in the Geogebra files
