This booklet contains a wealth of differentiated materials for practicing and solidifying the basic written arithmetic operations. Children work with place value charts, practice semi-written and written addition and subtraction with and without carrying. They also multiply and divide step-by-step, semi-written and written, and train written division with remainders. To accommodate the various learning levels and competencies of all children, there are three worksheets for each exercise topic, each with a different level of difficulty. This allows for optimal differentiation and the perfect support for each individual student. The worksheets are oriented towards the students' everyday experiences and offer not only tasks to be solved in writing but also action-oriented elements and open-ended tasks—ensuring that there is something suitable for every learning type.
