The foundation for a successful start in mathematics! Circle and square, more and less, long and longer - important concepts and the secure grasp of quantities are fundamental prerequisites for success in early mathematics education. The worksheets provide a complete course for preparation. The mathematical learning process begins with understanding - quite literally with hands-on experience - and progresses from concrete to symbolic representation. For each focus area, there are several templates available, allowing concepts to be not only worked on but also reinforced. Cube picture cards, number lines, or action cards for quantity comparison - the materials in the appendix are just as tested and proven in school practice as the worksheets. This book is recommended for kindergartens and preschools, as well as for remedial or elementary schools.
