The Klippert series offers a systematic skills training based on the methodology of Dr. Heinz Klippert. Each booklet methodically presents two core or curriculum topics. Students work through various facets of a topic using fully developed lesson units with lesson plans and corresponding photocopiable templates/worksheets, thereby training important overarching competencies. They primarily learn to work independently and take responsibility for their own learning. This increasingly relieves teachers, allowing them more time to focus intensively on individual students. With the help of this booklet, you will train your students in the following competencies: - Understanding and confidently applying methods of semi-written/written multiplication and division - Automating the basic multiplication and division facts - Documenting and explaining calculation methods - Estimating results.
