All subjects shall help the pupils to understand the value system for learning. Critical thinking in mathematics includes critical evaluation of reasonings and arguments and can arm the pupils to make their own decisions and take a stand on important questions in their own life and in society. When the pupils are given the time to think, reflect, reason mathematically, ask questions and experience that the subject is relevant, the subject facilitates creativity and innovation. Mathematics shall help pupils to develop their ability to work independently and to collaborate with others through exploration and problem solving, and can help pupils to become more aware of their own learning. Giving the pupils the opportunity to solve problems and master challenges on their own contributes to developing perseverance and independence.
