Description
This book links elements to the Australian Curriculum with the use of a Geoboard to develop many geometry and measurement concepts. Explore the following mathematics concepts with geoboards and the aid of this book:
Shape: Properties of shape, angle, similarity and congruence
Location: Position co-ordinates
Transformation: Reflection rotation and translation
Perimeter and area
This book explains how to get the most from a Geoboard. Geoboards provide the opportunity to explore geometry and measurement concepts, with a little algebra thrown in.
