GeoGebra Institute Maslama al-Mayriti (IGMM) is formed by a group of teachers, educators and students in Madrid (Spain). Our vision is to promote the use of GeoGebra and support the development and sharing of its materials in Madrid, and to nurture collaboration between teachers, educators and researchers for a self-sustaining community of practice. We organize GeoGebra workshops for teachers and students at different levels, and courses for Primary and Secondary teachers in order to promote the use of GeoGebra their Schools. We also promote the creation of new curriculum materials in cooperation with other GIs in Spain. Let's visit our website to see our curriculum and workshop materials.
