### THINKING MATHEMATICS! Vol 1: Arithmetic = Gateway to All!

This is the first book of a multi-volume series exploring joyful mathematics thinking and doing. Written for educators, high-school students and math enthusiasts of all ages and all backgrounds, this text starts at the very beginning of mathematical thinking – counting – and gradually unveils layers of understanding and wondrous delight through the power of thinking deeply about simple ideas.

Topics covered in this text include: the counting numbers, figurate numbers, the famous “exploding dots” activity, polynomials as numbers, divisibility results, the Euclidean algorithm, rational and irrational numbers, exponents and logarithms, infinity, and more.

Be sure to check out: THINKING MATHEMATICS! Vol 2: Advanced Counting and Advanced Algebra Systems for the continuation of this story. Volumes 3 onwards tackle the traditional topics of the high-school curriculum.

### Encyclopedia of Mathematics

Encyclopedia of Mathematics is a comprehensive one-volume encyclopedia designed for high school through early college students. More than 1,000 entries, numerous essays, and more than 150 photographs and illustrations cover the principal areas and issues that characterize this area of science. In order to provide a well-rounded, completely accessible reference, the author worked closely with teachers of all levels in developing subject material and a sound understanding of mathematical concepts, and on teaching analytical thinking.

### Mathematics Galore!

Mathematics Galore! Showcases some of the best activities and student outcomes of the St. Mark’s Institute of Mathematics and invites you to engage the mathematics yourself! Revel in the delight of deep intellectual play and marvel at the heights to which young scholars can rise. See some great mathematics explained and proved via natural and accessible means.

### Solve This: Math Activities for Students and Clubs

Sophisticated mathematics is accessible to all. Solve This proves it! It is a collection of intriguing mathematical problems and activities linked by common themes that involve working with objects from our everyday experience. Learn about the mathematical mysteries of a bagel, a checkerboard, and a pile of laundry, for example. Discover for yourself that wheels need not be round, that braids need not have free ends, that it is always best to turn around twice — and more! Mathematics is all around us. We all do mathematics everyday.

### Weird Ways to Work With Pi

In this curious little text we’ll explore all sorts of curious little issues: What is the value of pi for a square? What can we say about ropes wrapped around the Earth? What is the “right” value of pi for any shape? Can the value of pi change?

Lots of mathematical fun to be had.
