Transformations and School Mathematics
JOHN DEL GRANDE
Transformations have played a very important part in our thinking over the past five years. Thinking about transformations has opened to us some of the true fascinations of mathematics and has showed us new directions for the development of student materials starting with five-year-old children. I am not alone in my enthusiasm for this approach.
