1. Construction of a system to teach, in an interactive way, how to do Euclidian constructions with ruler and compass in 5th and 6th elementary school grades. This project was implemented for the Latin American Institute for the Educative Communication. Enciclomedia Project. This software is divided into three parts, in the first one children watch step-by-step videos with 30 elementary ruler and compass constructions. In the second part the children manipulate virtual ruler and compass tools to meet a given construction objective and the system grades them when finish. The third part is intended to allow free geometrical constructions. The project development lasted 18 months with the participation of ten programmers, 2 graphic designers and 10 specialists in education.
2. Construction of an interactive problem pool to support the mathematics text books in 5th and 6th elementary school grades in Mexico. This project was implemented for the Latin American Institute for the Educative Communication. Enciclomedia Project. The system contains the programming of more than five hundred problems in which some parameters vary to give the students a wide collection of problems. When children cannot solve one problem the system gives them a detailed explanation of the solution. The development of this software lasted 18 months with the participation of 15 programmers, 1 graphic designer and 20 specialist in education.
3. Construction of a spread sheet special for children to be used in 5th and 6th elementary school grades in Mexico. This project was implemented for the Latin American Institute for the Educative Communication. Enciclomedia Project. This spread sheet has the basic characteristics of professional spread sheets, but it contains special characteristics to enforce children to use formulas. The system contains facilities to prefabricate sheet forms to specific lessons and to grade the children answers. The development of this project lasted 18 months with the participation of five programmers, 3 graphic designers and ten specialists in educations.
4. Interactive educative software to teach the concepts of area and perimeter in 5th and 6th elementary school grades. This project was implemented for the Latin American Institute for the Educative Communication. Enciclomedia Project. The system presents an square grid with colored images, there are five activities: 1. to determine de area of a given color, 2. to draw one image with a given color, 3. to calculate the perimeter of a given region. 4. to draw an image with a given perimeter and 5. to draw a rectangle with a given area. The project development lasted 2 months with the support of three programmers, one graphic designer, and five specialist in education. PDF
5. Interactive educative software to teach the scale concept in 5th and 6th elementary school grades. This project was implemented for the Latin American Institute for the Educative Communication. Enciclomedia Project. The system presents an square grid with colored images, there are four activities: 1. to duplicate the scale of a given image, 2. to half reduce a given image, 2. To determine the relative scale of two given images and 3. to find two images in a set that satisfy a given scale relationship. The project development lasted 2 months with the support of three programmers, one graphic designer, and five specialist in education. PDF
6. Interactive educative software to teach the concepts of surface area and volume in 5th and 6th elementary school grades. This project was implemented for the Latin American Institute for the Educative Communication. Enciclomedia Project. The system presents a 3-dimensional cube grid with solids, there are six activities: 1. to build a solid with a given volume, 2. to determine the volume of a given solid, 3. to determine the volume of a small parallelepiped by cutting it in slices, 5. to determine the volume of a big parallelepiped, 6. calculate the surface area of a parallelepiped by peeling the solid boundary, and 6. calculate the surface area of a given parallelepiped by opening the surface boundary. The system contains facilities to rotate and view from any angle the solids. The Project las four months and participated three programmers, one graphic designer and five specialists in education.

7. Interactive educative software to teach the symmetry concept in 5th and 6th elementary school grades. This project was implemented for the Latin American Institute for the Educative Communication. Enciclomedia Project. The system presents an square grid with colored images, there are four activities: 1. to determine the square which is symmetrical to a given square in the grid, 2. to determine the triangle which is symmetrical to a given triangle in the grid, 3. to complete a drawing in a symmetric way with respect to a given image and 4. to find all the symmetry axes of a given image. The project development lasted 2 months with the support of three programmers, one graphic designer, and five specialist in education. PDF
