This book, and the entire MY STEM DAY series, is packed with amazing challenges and do-at-home experiments with easy-to-follow step-by-step instructions for the activities and bite-size text detailing scientific facts and stats. The series is endorsed by a leading STEM educational consultant Math is everywhere! From morning until night, we see numbers and measurements everywhere. We need math to cook, to travel on time, to build things and to play music. We use math to describe the world around us in quantities. p> Imagine a world without math.
