Student Tasks: GeoGebra
These tasks are designed to help students in understanding mathematical relationships better through exploring dynamic constructions. They can be accessed using the computer-based version of GeoGebra or the tablet/smartphone app. They have been designed with the following structure:
- Construction: step-by-step guidance of how to construct the objects in GeoGebra.
- Questions for discussion: The emphasis is on students being able to observe mathematical relationships by changing objects on their screen.and being able to describe what happens, and explain why.
- Problem: The purpose is for them to formalise what they have learnt through exploration and discussion and apply this to a “standard” style question.
- Further tasks: Extension activities with less structure for students who have successfully completed the first three sections.

Between April and July 2019 MEI trialled the use of GeoGebra exam mode with a selection of schools and colleges. The materials included practice questions and guidance based on the pure content of AS Mathematics. These materials can be used by students to learn how to use GeoGebra to support their studies.

Problem solving activities using GeoGebra
These problem solving activities are constructions that test students' understanding of connections between representations and reinforce generalisation
