For teachers
In school education, Tetrakys can be used in either of two ways: First, Tetrakys can be a program to favor intuition and develop the intelligence of the child in primary school. Second, Tetrakys can be used as a didactic material in middle school.
In primary school, which has a flexible curriculum more centred on the children and their games, Tetrakys can be adopted progressively as suggested for non school education in the parents section.
It is suggested that the child should play freely during 20-30 minutes per day. Moreover, Tetrakys should be ready in the construction area to play with during activities. It is also recommended the establishment of a period for structured games where small teams could be coordinated. If the teacher develops a project program, games can be perfectly incorporated to this program. Didactic progression is flexible.
The teacher should have a game with the complete Tetrakys material not disarmed to expose all the basic rules of the games and challenges. It would be ideal for every child to have a complete game with which she could, individually, build and disarm their own constructions.
As didactic material for mathematical contents Tetrakys is centred on the process of learning, not its results. It has didactic characteristics as chromodidactics and comprehension through manipulation and verification. On any application modality, basic aspects of the pedagogic philosophy of Tetrakys must be considered.
In the Games and Challenges section suggestions and a didactic guide are presented. These suggestions and guide can be used on the school program.
