How to Be a Math Genius - Illustrated examples to show your kid the power, beauty, and joy of math

I enjoyed learning about statistics, probability, zero, infinity, number sequences, and more in this heavily illustrated kids’ book called How to Be a Math Genius, by Mike Goldsmith. But would my 11-year daughter like it as much? I handed it to her after school and she become absorbed in it until called for dinner. She took it to the dinner table and read it while we ate. The next day, she asked for the book so she could finish it. Loaded with fun exercises (like cutting a hole through a sheet of paper so you can walk through it), How to Be a Math Genius will show kids (and adults) that math is often complicated, but doesn’t need to be boring. (This book is part of DK Children’s How to Be a Genius series. See my review of How to Be a Genius.)
