Outline
Create , Visualize & Explore
This workbook was initially created for the workshop "Create , Visualize & Explore with GeoGebra and Desmos" for secondary and senior secondary mathematics teachers conducted on November 27 & 28, 2015. This workshop was held at Sanskriti School , New Delhi, India and led by Sangeeta Gulati.
Over the past years, I have created and curated many other useful applets related to CBSE curriculum for use of teachers and students. i am happy to share this resource with the participants of all of my workshops conducted in the past years and those which will be conducted in future.
