## What is e++ 3?

Students can build prisms/cylinders and pyramids/cones with different bases, and verify the validity of 'Euler's formula' by observing the numbers of vertices, edges and faces of each 3-D figure. Students can also form regular polyhedra and find out their respective 'dual polyhedra'.

Modern Educational Research Society develops a series of teaching tools and interactive App, to facilitate teachers in implementing scaffolding activities in class, and support students' self-directed learning at home.
