Algorithmization in a Computer Graphics Environment

Today’s digital age makes it possible for people to communicate via video or images. Therefore, computer graphics is part of the elementary school curriculum. The paper is aimed at updating computer science education at Czech elementary schools; it shows how pupils could develop their computational thinking when creating vector graphics based on basic geometric shapes such as a circle, ellipse, square, rectangle and others. The following methods were chosen to present the proposed processes: verbal expression for an algorithm, visual projection and a flowchart.
