Compound of Icosahedron and Dodecahedron 3. The Small Triambic Icosahedron 4. Compound of Small Triambic Icosahedron and Dodechedron 5. Left Pentagonal Icosatetrahedron 6. Compound of Left and Right Pentagonal Icosatetrahedra 7. Compound of Three Cubes 8. Compound of Three Tetrahedra 9. Compound of Five Octahedra 10. Wire-frame model of Compound of Two Tetrahedra It also includes an introduction with sections on the mathematics behind the models; a short history of modular origami; a section on tools and folding techniques, and a gallery of the finished models that are presented in the book.
More Geometry Snacks
More Geometry Snacks, like its highly successful predecessor, is a mathematical puzzle book filled with geometrical figures and questions designed to challenge, confuse and ultimately enlighten enthusiasts of all ages. Each puzzle is carefully designed to draw out interesting phenomena and relationships between the areas and dimensions of various shapes. Furthermore, unlike most puzzle books, the authors offer multiple approaches to solutions so that once a puzzle is solved, there are further surprises, insights and challenges to be had. As a teaching tool, More Geometry Snacks enables teachers to promote deep thinking and debate over how to solve geometry puzzles. Each figure is simple, but often deceptively tricky to solve - allowing for great classroom discussions about ways in which to approach them. By offering numerous solution approaches, the book also acts as a tool to help encourage creativity and develop a variety of strategies to chip away at problems that often seem to have no obvious way in.
Valeskas
An incantation transferred a Dragon Lord’s spirit into a human’s body. Can two companions reverse it before it becomes permanent? A dark priestess, intent on escaping through an enchanted door into another world, invokes a dragon from his prison, The Void, into the human body of a pirate so he can locate and capture a young but powerful light goddess to assist her in gaining her freedom. However, the longer the dragon stays in the pirate’s body, the more human he becomes, and as he frantically searches for the young goddess, she is also searching for him to break the priestess’s enchantment and send him back to The Void, and free the pirate. This fourth and final book in the Dragon’s Tear Chronicles follows the stories of Kaida and Meelay as they attempt to break Hariah’s enchantment and return the Blood Dragon, Valeskas, to The Void.
Artful Math Activity Book
The wonderful thing about mathematical art is that the most beautiful geometric patterns can be produced without needing to be able to draw, or be 'good at art'. Mathematical art is accessible to learners of all ages: its algorithmic nature means that it simply requires the ability to follow instructions carefully and to use a pencil and ruler accurately. It is engaging, enriching, thoroughly enjoyable and is a great leveller in the classroom. Learners who may not normally shine in mathematics lessons will take your breath away with their creativity. Those who struggle with their mathematics will experience the joy of success through their mathematical art-making. The six Artful Maths activi...
The Case of the Missing Servant
The first in a detective series that “immediately joins the No. 1 Ladies’ Detective Agency as representing the best in international cozies” (Booklist, starred review). Meet Vish Puri, India’s most private investigator. Portly, persistent, and unmistakably Punjabi, he cuts a determined swath through modern India’s swindlers, cheats, and murderers. In hot and dusty Delhi, where call centers and malls are changing the ancient fabric of Indian life, Puri’s main work comes from screening prospective marriage partners, a job once the preserve of aunties and family priests. But when an honest public litigator is accused of murdering his maidservant, it takes all of Puri’s resources to investigate. With his team of undercover operatives—Tubelight, Flush, and Facecream—Puri combines modern techniques with principles of detection established in India more than two thousand years ago, and reveals modern India in all its seething complexity.

Curve Stitching
Curve stitching is a creative, practical activity with a strong mathematical background. This book explains the technique and there are large colour photographs of a good selection of beautiful designs, with stitchbystitch sewing plans. The different families of designs are put into their mathematical context and there are many suggestions for further development. There is also a good collection of computer programs written in Basic. These programs can readily be modified and adapted so that one can find on screen those patterns which will be most pleasing to sew.
Origami Dots
This book is a collection of intriguing mathematical challenges that come from folding paper. All the challenges are the same, fold the corner of the paper to a given dot and find the area that remains uncovered. Despite the same question, a small move of the target dot can drastically change the logic needed to find the solution to the challenge. So the problems become increasingly complex, with possible solutions involving Pythagoras' and similar triangles as well as trigonometry and algebra. Insights learnt from earlier challenges can help with those that follow. However, if at point the challenge becomes too great, the answers can always be found by measurement with a ruler and directly ...
The Shattering
Keri, Janna and Sione have two things in common: they each have an older brother who committed suicide, and they each have a connection with Summerton. As the three teenagers delve deeper into the mystery they uncover secrets that will shatter everything they thought they knew.
