Mathematics is a lesson in abstract models and the relationships between them, a science, a way of thinking, an art, a language and a tool of carefully defined terms and symbols. Mathematics is defined as the abstract form of life in its simplest form. However, our life is intertwined with mathematics. In our body, in our nature, in the technological tools we use, in the meals we make, in sports,… In short, it is possible to come across mathematics in every part of our daily life. With "Realistic Mathematics Education", our project was created to show our students that mathematics is related to situations in life and that it is actually close to students, and to compare students with real life problems and produce different solutions. Our students will learn to do mathematics in a holistic way by using mathematical modeling based on real-life situations given in cooperation and will be able to explore life with mathematics.
