The support booklet Mathematics for Grade 4 specifically promotes the prerequisites that children with learning difficulties or weaknesses in certain areas need to build a basic understanding of mathematics. It trains the areas of perception, motor skills, number comprehension, understanding of mathematical operations, and the decimal place value system in a spiral manner. With this workbook and the included supplements, children can work independently in class, in special support sessions, or at home. The answer booklet for quick self-checking can be easily detached with one motion. The proven sticker reward system provides an additional incentive for the children: for each completed page, the child is allowed to place a sticker on a busy picture.
