The mathematical fields of knowledge include numbers and understanding numbers, algebra, functions, geometry, statistics and probability. The pupils shall early gain a strong concept of numbers and develop a variety of numeracy strategies. Algebra refers to exploring structures, patterns and relationships, and is an important prerequisite for enabling the pupils to generalise and model in mathematics. Functions provide the pupils with an important tool for studying and modelling change and development. Geometry is important for enabling the pupils to develop good spatial understanding. Knowledge of statistics and probability gives the pupils a good foundation for making choices in their own lives, in society and in working life. The fields of knowledge form the basis the pupils need in order to develop their mathematical understanding by exploring relationships within and between the mathematical fields of knowledge.
