An individual Maths Fair item at High School and Higher Secondary/VHSE in which a student builds dynamic geometry constructions in GeoGebra, scored out of 100.
This item asks students to use GeoGebra, free dynamic mathematics software, to construct and explore geometry. Dragging a point and watching a property stay true is the idea: a construction that changes shape but keeps its relationship.
In the The Kerala School Sasthrolsavam Mathematics Fair (Ganithashastramela) it is an individual item at High School (classes 8-10) and Higher Secondary/VHSE (classes 11-12), open to girls and boys.
Technical excellence and effective use of tools carries 40 of the 100 marks, so mastery of the software matters most. The other lines cover textbook concepts and continuity, attractiveness and composition, and communication.
Students present on a computer, showing how the construction was built and what it reveals.

- Technical excellence, effective use of tools (40): command of constructions, sliders and tools.
- Excellence in presentation and ability to communicate ideas (20): clear explanation.
Treat these as the judging focus, not a fixed rubric: publish your own weighted criteria for Construction Using Geogebra Software under Scoring Setup, or start from the judging and scoring software guide.
How to prepare for Construction Using Geogebra Software
How entrants and their teachers usually get Construction Using Geogebra Software right on the day:
- Learn the construction tools and sliders thoroughly.
- Plan the construction on paper first.
- Test by dragging every free point.
- Use colour and labels to guide the viewer.
- Prepare a three-minute walkthrough.
- Save backups and carry the file on two devices.
- Practise explaining what stays constant when you drag.
- Idea to try: show that the angle in a semicircle is a right angle by dragging a point
- Idea to try: a dynamic triangle with its centroid, circumcentre and orthocentre
- Idea to try: a rotation animation of a polygon
