With Professor Kortenkamp's learning blocks, primary school students can build real number pyramids, which they previously only knew on paper in their textbooks. It's a simple principle: the numbers of two adjacent blocks, when added together, equal the number on the block above. Number pyramids have proven to be a productive activity in primary school math lessons. Professor Kortenkamp's unique learning blocks add a new dimension to this proven learning concept, allowing children to build number pyramids themselves instead of filling in blanks on paper. Interactive use allows for playful practice of addition and subtraction. The different colors of the blocks make it easy to experience, discover, and explore mathematical relationships and rules. The research tasks and practice materials in the textbook offer a variety of ideas for working with number pyramids, provide insight into mathematical phenomena, and also promote process-related skills such as discovery, explanation, invention, investigation, argumentation, and communication. Whether in the classroom or for homeschooling, the learning blocks are delivered in a high-quality case with a carrying handle, so the building blocks can be quickly packed away again after learning math and the world of numbers can be taken anywhere.
