  Jo Boaler, What's Math Got to Do with It? How Parents and Teachers Can Help Children Learn Their Least Favorite Subject. Penguin 2008.

"Jo Boaler shows that math is understandable, and that it can be fun to get your head around it - but that it's often taught in ways that make it dry and deadly. She points to the beauty and joy of mathematics, and ways that math classrooms can become centers of lively mathematical thinking. American children deserve a richer mathematical diet than we've given them, and Boaler shows how and why." (Alan H. Schoenfeld)

"Through her comprehensive, penetrating study of the mathematics departments in two English schools, Jo Boaler shows how mathematics teaching and learning are shaped by teachers and by the settings in which they work." (Jeremy Kilpatrick)

Real numbers, complex numbers, quaternions - what's next? The first part of the book is quite accessible, but the going gets tougher in the later chapters.

"Provides a self-contained introduction to complex numbers and college geometry written in an informal style with an emphasis on the motivation behind the ideas ... The author engages the reader with a casual style, motivational questions, interesting problems and historical notes." (Mathematical Reviews)

• Felix Klein, Elementary Mathematics from an Advanced Standpoint: Arithmetic, Algebra, Analysis. Dover 2004.

"Written in 1932, Klein's Elementarmathematik lectures was intended as a survey of mathematics for those who already knew most of the technical detail, especially future teachers, but who perhaps lacked a good understanding of mathematics as a whole. The lack of a broad perspective is probably at least as big a problem today as it was then, so Klein's text is still valuable. Klein also frequently discusses historical and pedagogical aspects, and the tone is quite informal throughout." (Viktor Blasjo)

A classic written in the 1920s. An axiomatic construction of numbers and concise derivation of their fundamental properties, from the natural numbers to the complex numbers.

Moses was already a venerable civil rights campaigner when he embarked on what became an illustrious career in education and mathematics. He has now returned to Mississippi to teach math to descendants of the sharecroppers he helped mobilize 40 years before. With journalist and fellow activist Cobb, he tells his personal story and shares his vision of universal math literacy among poor and minority children. He founded the Algebra Project. (Book News)

"A superb development that starts with the natural numbers and carries the reader through the rationals and their decimal representations to algebraic numbers and then to the real numbers. Along the way, you will see characterizations of the rationals and of certain special (Liouville) transcendental numbers."

"Aczel's compact and fascinating work of mathematical popularization uses the life and work of the German mathematician Georg Cantor (1845-1918) to describe the history of infinity of human thought about boundlessly large numbers, sequences and sets."
