Abstract
The
appropriate use of technology in mathematics teaching can greatly support
teaching and learning of mathematics. On the one hand technology can be
supportive in learning how mathematical knowledge can be used, while on
the other hand it offers an essential support to the appropriate development
of mathematical concepts. Geometry is an important part of school mathematics
 it is an area in which the students learn to build a mathematical (geometrical)
model of real situation already in early school years. Therefore it is
of great importance that the geometrical concepts are developed appropriately
 in terms of basic mathematical concepts, which will be built upon in
the next 810 school years. Dynamic Geometry Software (DGS) offers tools
and possibilities, which can considerably improve teaching of basic geometrical
concepts in the primary (as well as in higher) grades. We use Cabri Geometre
II to show, discuss, and analyze examples on how DGS can support development
of generic geometrical concepts in the first years of learning mathematics.
