Review
My kids have been participating in the Purple Comet Math Meet for the past 4 years. As homeschoolers, finding opportunities where they can work together on a team to solve interesting problems was never an option until the Purple Comet came along. The problems themselves are great preparation for AMC contests and cover a wide variety of topics, however, this book starts training the kids to problem solve at the middle school level and guides them all the way to high school level problem solving. Topics like Number Theory and Combinatorics become accessible to a younger generation while exciting their interest in math. We love having so many of these problems together in one book, especially since we missed the earlier competitions. The authors' experience in problem writing is evident by the elegance of the concepts they introduce. We love this book! --David Cordeiro

More great problems for Middle School and High School students.
By Thomas
Titu Andreescu is a catalyst for excitement in math for the young and talented. This collection of problems from an online contest is another of his additions to the fun awaiting those who are willing to take a chance. It is nice to have the problems all in book format. The problem sets cover a wide range of type and difficulty.

Innovative math ed design and implementation
By Maria Droujkova
What is a math meet? The traditional big events for problem-solving Math Circles are math competitions. There are many competitions, but Purple Comet! math meet stands out because of its clever, modern design. As other quality competitions, Purple Comet! offers children original, meaningful, interesting, tricky problems that are a joy to solve – that is, real mathematics. But there is more:

1. Global network, local communities. Purple Comet! is an international festival and an online event – but it consists of local experiences with friends. The global network generates energy, problem-posing support, and the sense of scale that a local circle would not achieve alone. But local communities provide the depth of discussion, camaraderie and nurturing that a global network lacks. Together, the two aspects work their magic.

2. Teamwork. The vast majority of math and science is done collaboratively, but children often take tests and competitions alone. Purple Comet! invites teams to solve problems together, only competing against other teams. This allows for more interesting types of problems. For example, some problems require insight, which is more likely to happen in group brainstorming. Other problems split into multiple sub-problems, so each person can tackle a piece of the bigger puzzle.

3. Technology is welcome. While doing things by hand can be artistic, quaint, or cute, most children who love science and math, and of course all STEM professionals, use computational tools in their problem-solving. Purple Comet! problems are designed with computing devices in mind. The problems focus on ingenuity and reasoning, rather than memory or computation. However, many problems are based on number patterns, so students learn to appreciate how numeracy and computational fluency help in problem-solving.

4. Self-checking. The design principle of self-checking goes back to Montessori. All problems have nonnegative integer answers. At the beginning, this principle made it easier to program Purple Comet! software. By now, it became an appreciated tradition. If a team gets a different sort of answer, they know to rework the problem. The known format of an answer is a hint, but not a big reveal, like knowing the correct answer would be.

To share the joy, Titu Andreescu and Jonathan Kane of the appropriately named AwesomeMath assembled problems from the first ten years of Purple Comet! math meet in a hardcover book with beautiful, clean layout of formulas and diagrams. You can use the book as a source of problems for family math or Math Circles. If you are a designer, the collection will be a valuable source of strong practices in curriculum development centered on problem-solving.
