A series of geometry focussed lessons for secondary school mathematics.By Michael O'ConnorGeometry and Beyond with Mathomat is a series of lessons for secondary school mathematics which make extensive use of commonly available classroom materials, such as the Mathomat (TM) template and dynamic geometry software.Geometry is one of the oldest areas of mathematics and it runs as a continuous thread throughout the mathematics curriculum. Geometry is present from children's first encounters with shape and remains a part of mathematics learning through to the development of formal proofs.Geometry and beyond with Mathomat is not a comprehensive text on geometry; it is a collection of activities, using common classroom tools such as MATHOMAT, that guide student development of key concepts that link to the bigger picture.The five areas in this book are: using units of measurement, shape location and transformation, Pythagoras and trigonometry, and geometric reasoning.The selected concepts that are used to explore these areas are linked together, if there is a gap in the knowledge or understanding of one concept then the ones that follow will be harder to grasp. However, it is always the role of the teacher to consider what activities the students need to explore.Activities in this book encourage communal understanding and consensus and always conclude with discussion of key points.Summary: Suitable for secondary school students. Geometry focus. Make extensive use of commonly available classroom materials, such as the Mathomat (TM)template and dynamic geometry software
