Learning objectives:

To work with the GeoGebra app and construct triangels and other geometric shapes. To realize how lenghts and arcs are changing when you move one corner point.

Implemented digital tools:

geogebra org, GeoGebra ( a free geometry app).

Supported digital competence for student:

Digital content creation, Problem solving

Elaboration of the competences:

Students create points, routes and triangels with the help of online information. The students solve problems and write down how they constructed a specific geometric shape,


Look for a useful explainer video in Create three problems for the class to solve.


Students work in pairs on a computer. The students watch the explainer video to learn how to work with the app.


Students choose one of the three given problems. The students solve the problem and write down their solution to the problem for the class to see.


Students present their solution to the problem to the class.

Implemented needed devices:

A computer or a laptop for the learning and practial phase, a mobile phone and a tablet only for the practial phase
