Interesting sharing by Vincent Wei Sern Lew on the use of dynamic mathematics and geometry software, in particular in using Geogebra.

The tutorials are easy and intuitive enough for students to learn without taking up too much of curriculum time as the students can explore after the teacher demonstrate the use.
