Acute Angle and Peter Perpendicular

Follow the adventures of Acute Angle and Peter Perpendicular in this cute rhyming story aimed at educating children about the wonders of geometry. Acute comes across Peter who has been run over by an Octahedron. She goes to find Mr Geometry who gives Peter a special tessellated triangle which has unique properties. But when he tries it on, something magical happens.In my role as a relief teacher (substitute), I had the opportunity to teach students some geometry words in English. "Mr, how come we are learning geometry in English?" one student asked. "Geometry is also English" I answered, but they were not convinced, so I offered to tell them a story, which I made up on the spot about Acute Angle who met Peter Perpendicular, who was sad because he had been run over by an Octahedron and was quite a mess with his lines intersecting at funny angles.As a result of this lesson, which was enthusiastically received by the kids, who laughed loudly at my ridiculous acting as I told the story, I thought it would make a great educational book and this book is the direct result.
