Math Magic (Ages 11 and Up) Math Magic 11 Years and Older Edition features techniques for left-to-right addition for two and three digit numbers, reverse addition (subtraction), and cross and box multiplication. This version also features computing squares, extracting cube roots, and calculating the day of the week for any given date.
The Human Calculator, Scott Flansburg, created Math Magic to confront the biggest math problem in this country: innumeracy. Most schools teach math the same way it has been taught for more than 100 years. But the fact is that not all people learn the same way, even if taught the same way. The Human Calculator believes that if people can see numbers in a different way, they can learn just how easy and how fun they are to work with every day.
Math Magic is the culmination of Scott's teachings presented in a stress-free way to help students, teachers, and parents with basic math skills. If you are looking to help improve your child's math skill and your own math skills, then Math Magic Number Secrets of the Human Calculator is the right tool for you!
