MYP 5 (Extended) has been designed and written for the IB Middle Years Program (MYP) Mathematics framework. The textbook covers the Extended content outlined in the framework. This book may also be used as a general textbook at about 10th Grade level in classes where students complete a rigorous course in preparation for the study of mathematics at a high level in their final two years of high school. We have developed this book independently of the International Baccalaureate Organization (IBO) in consultation with experienced teachers of IB Mathematics. The text is not endorsed by the IBO. by: Michael Haese, Sandra Haese, Mark Humphries, Edward
