This book is a teaching aid for the school book of Geology - Geography A' Gymnasium and it is a particularly comprehensive and functional study tool for both the Student Book and the Workbook of the lesson. It was created with love and interest for children who start their journey in high school and are in the A' grade, with the aim of offering them:
- reliable and valid support to successfully meet their school obligations for the subject of Geology-Geography.
- the ability for substantial learning of the material they will be taught.
It is also addressed to both colleagues who teach children of this grade and parents with the aim of constructively enhancing their teaching work and their effort to help children, respectively.

Each lesson of the book is developed as follows:
- I learn the main points (short text with important parameters of the lesson).
- I study with questions (development of the lesson with questions and answers, so that the child acquires supportive knowledge, can collaborate with classmates and has the ability to review important points during individual study).
- I answer the activities of the school book (detailed answers and tips for the activities in the classroom).
- I check what I have learned (original questions, 200 in total, both open-ended and closed-ended, for a more thorough understanding of the lesson, with the answers at the end of the aid).

At the end of each unit of lessons in the book there are:
- Interesting texts titled "Enriching my knowledge" which provide informational material that expands the children's horizons.
- Recap questions (correspond to the "Indicative Evaluation Topics" of the school Teacher's Book and their answers are at the end of the aid).
- Review tests (original questions, both open-ended and closed-ended, for a more thorough review of the unit of lessons, with the answers at the end of the aid).

The book also includes:
- Answers-Guidelines for the Worksheets of the school Workbook.
- Useful addresses for Geology and Geography on the internet.
