In modern education, an important role is played by the ability to apply mathematics in real life, to increase the motivation of students to study mathematics. The idea of the project is to enable children to compose their own math games, create and select tasks in algebra and geometry, mathematics, and use various digitalization resources. Students will work in mixed teams, introduce the material they know themselves, teach other partners and learn a lot. The main result of the project will be e-books made in canvas and on a story jumper, which will tell you about what electronic resources they used to create their math games. This material will be useful not only for children, but also for teachers for playing with students of the classes in which they teach. All partners - students will be familiarized with the results of the project and joint work at the joint festival "Our Ideas", which will be held remotely.
