Development of substitution thinking

The focus of this book is on enhancing pupils' mathematical thinking rather than merely teaching them to memorize procedures. It emphasizes the importance of understanding the "why" behind calculations, which helps students see mathematics as interconnected rather than isolated tasks. By fostering substitutional thinking, students gain a broader perspective that allows them to approach and solve various problems creatively. This approach promotes mathematical freedom and equips learners with the skills to tackle complex tasks effectively.
