Students have early length experiences must develop an awareness of what length is, and of the range of words that can be used to discuss length. Young children usually begin by describing the size of objects as big and small. They gradually learn to discriminate in what way an object is big or small and use more specific terms. The use of words such as long, short, wide, close, near, far, deep, shallow, high, low and close, focus attention on the attribute of length.
