**Teaching using Geogebra in the classroom (student textbook and teacher handbook)**

Student textbook and teacher handbook for teaching Mathematics with Geogebra - can be used to start with any grade from 6 through 10

- ICT student textbook/Explore maths with Geogebra level 1
- ICT student textbook/Explore maths with Geogebra level 2
- ICT student textbook/Explore maths with Geogebra level 3
- ICT Teacher handbook

IT for Change developed the student textbook and teacher handbook for the state of Telangana, India, with support from Commonwealth Educational Media Centre for Asia (CEMCA), an associate of Commonwealth of Learning.

This article by Dr. Sanjaya Mishta explore how institutional capacity building can be a determinant for the effectiveness of OER based e-learning.

This handbook introduces teachers to the use of different technology tools available for teachers for creating lessons, in their teaching-learning as well as for their planning. This is a COL publication.
