The Klippert series offers a systematic skills training based on the methodology of Dr. Heinz Klippert. Each booklet presents two core or curriculum topics methodically. Students work on various aspects of a topic using fully developed lesson units with lesson plans and corresponding photocopiable templates/worksheets, thereby training important overarching skills. They primarily learn to work independently and take responsibility for their own learning. This approach increasingly relieves teachers, giving them more time to focus intensively on individual students. With the help of this booklet, you will train your students in the following skills: - Extracting number words from stories - Creating an exhibition for number-quantity matching - Learning addition and subtraction - Representing calculation stories with images - Acquiring calculation strategies - Number puzzles.
