Application: In the 10-omat & 100-Net Student Book, you will find diverse and differentiated exercises for number range extension, addition, and subtraction up to 99. Thanks to various methodological approaches, students can easily approach the content according to their personal cognitive development (action, image, symbol, and language). To support the investigative approach, the concept of students as math detectives has been introduced. At the end of each chapter, there is a sticker as confirmation of what has been learned, which the children can stick on the certificate at the end of the first or second part. This approach allows for celebrating the learning process.

Learning Environment: The 10-omat & 100-Net Student Book is suitable for use both in the classroom and for remedial teaching – in small groups or individually.

Variants: The 10-omat & 100-Net Book explores the number range up to 99 using the 10-omat and the 100-Net as tools. Additionally, there is the 100-Net Book, which focuses on working with the 100-Net. Both books are available as student books and as teacher books, which provide deeper insights into the mathematical background and offer many additional suggestions for activities, exercises, and tasks, as well as solutions for the student book. All books are also available as eBooks.
