Mathematics 3rd grade. Arithmetic world to 1000. tasks and games

In the third volume of the practical workbook series on Dienes material, the focus is primarily on helping children gradually detach from the material and perform calculations independently. To achieve this, mathematical visualization is further developed through numerous tasks and games. In this volume, the number range is expanded to 1000, and children are introduced to written calculations as well as suitable calculation strategies in the higher number range. Throughout this process, great care is taken to ensure that children truly understand what they are doing. The Dienes material continues to provide valuable support in this regard.
