The Trends in International Mathematics and Science Study has shown that American schools have consistently helped students understand algebraic and statistical concepts, leading to high achievement internationally. Now it's time to do the same for geometry. Mark Driscoll, author of the powerful and popular Fostering Algebraic Thinking, takes up the challenge and leads you to new, research-based ways to improve how your students conceptualize and apply geometric ideas. With Fostering Geometric Thinking any math teacher can discover essential, practical ideas for helping students cultivate geometric habits of mind that lead to success in this crucial mathematical subject. The book focuses on rigorous, problem-based teaching that encourages students to deepen their thinking in three key geometric strands: geometric properties geometric transformations measurement of geometric objects. Fostering Geometric Thinking shows you how the interplay of these strands helps students devise multiple solutions and develop a broader sense of geometric principles. It's loaded with helpful resources, including: engaging problems to use in your classroom examples of student solutions to these problems transcripts of classroom interactions online resources featuring in-the-field footage of students working through open-ended problems highlighted in the book. Geometry is a vital component of mathematical understanding, and it's time that it received the same attention that algebra and statistics do. With engaging problems and straightforward suggestions that can help students deepen, recognize, and describe their thinking, Fostering Geometric Thinking is the resource you need to ensure that when it comes to geometry, your students know all the angles.

Here's everything you need for powerful professional development in one place: "The Fostering Geometric Thinking Toolkit." Based on the popular "Fostering Geometric Thinking, "the "Toolkit"'s 20 two-hour sessions provide a year's worth of math PD for middle and secondary teachers. Its facilitator- and participant-friendly sessions cover the key topics of "Fostering Geometric Thinking" geometric properties, transformations, and measurement. With "The Fostering Geometric Thinking Toolkit, "you'll lead teachers through hands-on opportunities to: develop new understandings of middle and secondary students' geometric thinking through a field-tested geometric habits-of-mind framework broaden and express their own geometric thinking by solving rich problems observe students' thinking and problem solving through in-the-classroom footage practice analyzing student work apply all they've learned in the sessions to engage students' thinking more effectively. "The Fostering Geometric Thinking Toolkit" fully supports you. Its facilitator materials provide clear instructions and include agendas, facilitator notes and tips, and other helpful resources. Its accompanying DVD goes above and beyond with an array of essential tools, including: numerous video clips for use in the sessions PowerPoint slideshows that summarize existing research on students' geometric thinking printer-ready participant handouts geometry applets for use by both participants and their students. Use "The Fostering Geometric Thinking Toolkit" and help your participants discover powerful ways to lead students to a new understanding of geometry.
