Informative videos- How to work in groups with GeoGebra on line

In this activity you are working in groups again. We are going to make our constructions. We will disvover the golden number in these constructions making the appropriate measurments. You will be asked to solve two activities in Geogebra. The three teams are exactly the same groups you have worked before.

Since you are not very familiar with Geogebra and Geogebra groups, the following videos will be useful for you.

The first one is how to work in groups using Geogebra, the second one is a video explaining how to draw a golden rectangle,  the third one is a video explaining about taking measurements using Geogebra, the forth one is how to adjust a picture in a golden rectangle
