In this contribution How a pupil becomes a teacher I will present chosen samples of lessons, which were performed by pupils teaching each other math contents. Pupils were using math e-textbook with iPads, program Geogebra with desktop computers and different math aplications (Quick Graph, Free GraCalc, Math Solver) with iPads. Pupils became teachers during the cooperative learning. They were exploring mathematical contents in groups. Pupils divided each other in first groups, where each pupil got different task. All pupils with the same task formed new groups. Divided this way they were researching mathematical contents with e-textbook Vega 1 and math aplications with iPads. All pupils were active because, they returned to first groups and had to explain their task to each other. So every one of them became a teacher. Gifted pupils made a research paper where they drew geometric objects with program Geogebra. They introduced their research paper Euler line to their peers. They thaught their classmates how to use Geogebra in the computer lab with desktop computers. They prepared tasks for their classmates, guided them and helped them.
