The aim of this station training is to reinforce calculation methods for the two- and three-part rule and to independently apply them to realistic everyday situations. Active discovery learning is the focus. Transfer skills and flexible thinking are encouraged. Working at the learning stations is intended to lead students to take responsibility for their own learning. This way, they practice assessing their learning pace and organizing tasks for themselves. To keep your preparation effort as low as possible, all necessary materials are provided: display stands, worksheets, solutions, posters, and visual materials, short reflection sheets, orientation checklists, and overview posters for hanging. The materials are suitable for both a teaching unit and independent work. Ready to copy and get started!.
