Ella Baker School encompasses a body of knowledge, skills and procedures that can be used in a rich variety of ways: to describe, illustrate and interpret; to predict; and to explain patterns and relationships in Number, Algebra, Shape and space, Measures and Data. Mathematics helps to convey and clarify meaning. Its language provides a powerful and concise means by which information may be organized, manipulated, and communicated. These characteristics make mathematics an essential tool for the child and adult. At Ella Baker the application of mathematics in a variety of contexts gives people the ability to explain, predict and record aspects of their physical environments and social interactions. It thus enriches their understanding of the world in which they live. Indeed the application of increasingly sophisticated mathematics in a growing range of economic, technical, scientific, social and other contexts has had a profound influence on the development of contemporary society.
