Years ago, I met a Japanese professor who eventually became my adviser during my one and a half year stay in Japan. **CRICED, t**he institute he was working also develops mathematics software in elementary and secondary schools. Below are 5 of the math software that they have developed.

1.) **Grapes** – a graphing software that allows users to draw most functions discussed in the secondary curriculum.

2.) **Geometric Constructor** – a dynamic geometry software for teaching and learning geometry. Allows users to publish contents on the web.

3.) **DbookPro** – a tool for developing digital textbook. This can be done by scanning textbooks and or importing textbooks images. I have written two manuals of dbook (**basic** and **advanced**) and you can view the sample output of a dbook **here**. You can download dbookPro **here**.

4.) **Geometry Construction Language (GCL) Editor** – an xml-based software used for creating educational materials in Flash.

5.) **DGraph** – Used for making and editing graphs from data and equation.

I have only tried 2 of these software (dbookPro and Grapes), but you might want to explore all of them.
