This official Math Kangaroo book for 3rd and 4th grade students contains 312 entertaining problems and solutions from actual the Math Kangaroo Competition odd years, spanning 1999-2023, for a total of 13 tests. Each test consists of 24 questions divided into color-coded easy, medium, and difficult categories. The Math Kangaroo Competition is internationally recognized and takes place in over 100 countries worldwide with 6 million students participating. The competition is held once a year, always on the third Thursday in March, for any student in grades 1 to 12.

Many mathematicians have been drawn to mathematics through their experience with math circles: extracurricular programs exposing teenage students to advanced mathematical topics and a myriad of problem solving techniques and inspiring in them a lifelong love for mathematics. Founded in 1998, the Berkeley Math Circle (BMC) is a pioneering model of a U.S. math circle, aspiring to prepare our best young minds for their future roles as mathematics leaders. Over the last decade, 50 instructors--from university professors to high school teachers to business tycoons--have shared their passion for mathematics by delivering more than 320 BMC sessions full of mathematical challenges and wonders. Based on a dozen of these sessions, this book encompasses a wide variety of enticing mathematical topics: from inversion in the plane to circle geometry; from combinatorics to Rubik's cube and abstract algebra; from number theory to mass point theory; from complex numbers to game theory via invariants and monovariants. The treatments of these subjects encompass every significant method of proof and emphasize ways of thinking and reasoning via 100 problem solving techniques. Also featured are 300 problems, ranging from beginner to intermediate level, with occasional peaks of advanced problems and even some open questions. The book presents possible paths to studying mathematics and inevitably falling in love with it, via teaching two important skills: thinking creatively while still ``obeying the rules,'' and making connections between problems, ideas, and theories. The book encourages you to apply the newly acquired knowledge to problems and guides you along the way, but rarely gives you ready answers. ``Learning from our own mistakes'' often occurs through discussions of non-proofs and common problem solving pitfalls. The reader has to commit to mastering the new theories and techniques by ``getting your hands dirty'' with the problems, going back and reviewing necessary problem solving techniques and theory, and persistently moving forward in the book. The mathematical world is huge: you'll never know everything, but you'll learn where to find things, how to connect and use them. The rewards will be substantial. In the interest of fostering a greater awareness and appreciation of mathematics and its connections to other disciplines and everyday life, MSRI and the AMS are publishing books in the Mathematical Circles Library series as a service to young people, their parents and teachers, and the mathematics profession.

This comprehensive introduction to probability and statistics will give you the solid grounding you need no matter what your engineering specialty. Through the use of lively and realistic examples, the author helps you go beyond simply learning about statistics to actually putting the statistical methods to use. Rather than focus on rigorous mathematical development and potentially overwhelming derivations, the book emphasizes concepts, models, methodology, and applications that facilitate your understanding.

A companion series to our "Competitive Mathematics for Gifted Students," the series "Math Challenges for Gifted Students" offers additional material in practice test form. The workbooks are useful for assessment and for development of testing skills. In full color and with fully detailed solutions, the workbooks may be used as a fun introduction to competitive problem solving. However, the problems are a bit more difficult than actual Kangaroo problems, exploring a large number of known 'tips and tricks.' One could say it is much more concentrated in that, unlike actual exams, it has less 'filler' - almost every problem is 'tricky' and embodies a specific strategy. The material is excellent for training purposes and has been used by the authors in seminars with hundreds of the most gifted students in the Bay Area. The workbook contains six 24-question tests. After each test there is an answer key. The tests are followed by detailed solutions. The recommended time limit for each test is of 75 minutes. Students who have not been exposed to competitive problem solving will find this book extremely difficult and will need help from an adult. Without preparation, students who get 'A' in school generally score about 50 points out of 96 possible on Kangaroo level 1-2.

The mathematics education community continues to contribute research-based ideas for developing and improving problem posing as an inquiry-based instructional strategy for enhancing students’ learning. A large number of studies have been conducted which have covered many research topics and methodological aspects of teaching and learning mathematics through problem posing. The Authors' groundwork has shown that many of these studies predict positive outcomes from implementing problem posing on: student knowledge, problem solving and posing skills, creativity and disposition toward mathematics. This book examines, in-depth, the contribution of a problem posing approach to teaching mathematics and discusses the impact of adopting this approach on the development of theoretical frameworks, teaching practices and research on mathematical problem posing over the last 50 years. ​​

Web Programming with HTML5, CSS, and JavaScript is written for the undergraduate, client-side web programming course. It covers the three client-side technologies (HTML5, CSS, and JavaScript) in depth, with no dependence on server-side technologies.
