One of the important educational efforts always been emphasizing of the mathematics internal integrity. Its advantages are well known. Unfortunately, the software used in mathematics teaching is explicitly separated by application areas. As an example, here is a fragment from the Topics of Interests of current conference: Geometry using Dynamic Geometry software, Algebra using CAS, Graphics Calculators, and Statistics using Dynamic Statistics software. Such multitude disturbs teaching because of disintegration both studied subjects (Mathematics Contents) and software interfaces (GUI). This paper provides a unified software support by means of ''VisuMatica''- a tool developed for mathematics teaching in integrated manner. Multiple examples of its application in teaching different subjects of high school and academy mathematics courses demonstrate the power of integrated approach.
