ROBOT MOWAY IN THE SCHOOL COURSE OF INFORMATICS
The article presents a lesson in which the concept of the algorithm is fixed as a sequence of actions of a performer. Linear and cyclic basic algorithmic constructions are realized using Moway robot. The movements of the robot along the trajectory of the right shapes are studied. The lesson includes a mathematical unit for calculating the angle of rotation of the robot. Variable is studied in the Scratch program.
