 Hi, my name is Sylvia. I teach in one of the high schools in Rojdal. I want to share with you how we use the book Exploring Geometry with a nine-pin circular jaw board in our scheme of learning. We start with year seven when in the last unit shouldn't explore angles, triangles, measuring angles and as well the use of appropriate mathematical language. In year eight students explore four-sided shapes and parallel lines. I want to show you an example of our students' work when students were encouraged to describe what they found what they can see. This is another example when students as well use the mathematical notation. We again come back to use this book in year 10. In year 10 we use this book to introduce and explore certain theorems. This is another example of our student book. We have been using this book for the past four years and we believe that this approach helps our students to understand this concept. Thank you for listening and bye.
