Read, combine, solve - a tricky math fun for in-between: Students read information on the topics of numbers and their representations, measurements, arithmetic operations, statistics and probability, as well as geometry. They skillfully combine the clues contained within and arrange them in a logical sequence. Only then can the posed question be answered. While working on the logic puzzles, students train a systematic and combinatorial approach. Their reading and thinking skills are improved and reinforced, and furthermore, the logic puzzles promote students' reading competence, which is also an interdisciplinary teaching principle that includes mathematics instruction. All logic puzzles are offered in two differentiated levels of difficulty: students must read up to nine sentences in one case and up to eleven sentences in another to arrive at the solution.
