Understanding the essence of mathematics through hands-on experience: joy of play, aesthetics, fascination, insight - this is the essence of mathematics. For many children, the first encounter with mathematics takes place in elementary school. But what should this initial contact look like to foster a happy and lasting relationship with counting and calculating from an early age? This volume provides suggestions for discovery-based learning by not only illustrating mathematical concepts but also making them literally 'graspable.'

The book enables an interactive and group-dynamic experience both inside and outside the classroom. Using peas and toothpicks, the world's most natural and cost-effective construction system is created. Complex structures are built, allowing for an understanding of mathematics through the handling of everyday objects and materials.

Soap bubbles become the subject of mathematical exploration. Similarly, stationary and rotating shadows are examined, simply illustrating the idea of projection. There are tangible equations that can be solved through action, and by slicing a pizza and diluting juice, a glimpse into infinity is attempted - accompanied by illustrative visual material.

This book is a reissue of the out-of-print volume 'With Peas and Toothpicks to Mathematics.' It is aimed at educators teaching mathematics in elementary school who wish to introduce their students to the fascinating world of mathematics using the simplest means.
