Die Mathe-Knobel-Kartei 3.-6. Schuljahr. Fermi-Aufgaben

Teaching materials for students in elementary and secondary schools, subject: Mathematics, grades 3-6. "Would all the children in the school fit into this classroom?", "Could your great-great-great-great-grandfather have met Napoleon?" or "How tall is the stack of paper from all the copies made in a year?" With exciting questions like these, there are often no clear solutions - but plenty of puzzle fun! Sturdy cards featuring challenging Fermi problems in three difficulty levels, with solution hints on the back for approximating results, promote open and cooperative learning. In teams, children tackle the puzzles and practice all basic mathematical competencies without fear of making mistakes: creativity, cooperation, communication, and especially reasoning and justification. Independent thinking, problem-solving, and personal responsibility are encouraged.
