Prof. Kortenkamp’s unique learning blocks open up a new dimension to this proven learning concept, they give children the opportunity to actually build number pyramids themselves instead of filling in blanks on paper. In interactive use, addition and subtraction can be practiced in a playful way. The different colors of the blocks make it easy to experience, discover and explore mathematical relationships and calculation rules. The researcher tasks and practice materials in the textbook offer a variety of ideas for dealing with number pyramids, provide insights into mathematical phenomena and also promote process-related skills – discovering, explaining, inventing, researching, arguing and communicating. - 230 stuks (120 witte bouwstenen en 110 gele bouwstenen) + tweetalig handboek, kopieersjablonen en poster Whether in the classroom or homeschooling, Prof. Kortenkamp’s learning blocks come in a high-quality case with a carrying handle, so the building blocks can be quickly repacked after learning arithmetic and the world of numbers can be taken anywhere.
