Thanks for invitation,

following our colleagues specialized answers, but I do believe that "teaching aids" is a part of the "teaching methodology science".

Teaching aids are tools, tools, and materials used by the teacher to improve the teaching and learning process.

- Visual means:

- Audio:

- Mixed media (audiovisual)

- Concrete means

I believe that it will all boils down to creativity. A simple teaching aid can be of great help as long as you can create an activity with an inspiring process of discovery that helps satisfy the natural curiosity with which we are all born.
