Das Übungsheft Rechentricks Mathematik 3/4

Curtains up for the best, most beautiful, and astonishing math tricks that will impress family, friends, classmates, and teachers. Admittedly, even the greatest magician needs a bit of practice. The practice book "Math Tricks 3/4" helps with that. And not only that! Step by step, children will learn techniques that allow them to solve operational task formats, such as number walls or calculation triangles, more quickly. In doing so, they independently acquire many sub-competencies of the process-related skills anchored in the curriculum and become true problem-solving professionals.

The competencies are built up in several stages: The children
• learn to approach tasks through experimentation
• systematically try out and recognize patterns
• use systematic trial and error to solve tasks purposefully
• understand the inner structure of the calculation formats
• apply this knowledge to solve problems directly

These contents are enlivened by special "magic pages." On these magic pages, children learn math tricks that they can perform at school, at home, or in their free time. First, they develop an understanding of the connection that makes the trick possible. Then, they are guided step by step on how to present the math trick. The following task formats are practiced:
• Number walls
• Calculation triangles
• Puzzle word problems
• Combinatorial tasks.
