Cliff will demonstrate how his speed math methods always prove faster than the old-fashioned algorithmic methods with which we all grew up. He’ll also show how these methods are often faster than with the use of a calculator! The directives of 3 of the Common Core Standards will play an important part in the discovery of these techniques. Many of these methods have long been in use in European and Asian schools and their textbooks, which explain why we currently find ourselves near the bottom ranking country in the world in mental math and calculation abilities. Once learned, however, these methods will help bring our calculating methods into the 21st Century and, at the same time, will leave your calculator-dependent friends in the dust!

Today, former 40-year math teacher Cliff Petrak of Chicago is going to help us master a multitude of little-known, super-shortcut computational techniques and strategies involving addition, subtraction, fractions, squaring and multiplication that will help bring our calculating methods into the 21st Century and, at the same time, will leave our calculator-dependent friends in the dust! Many of these methods have long been in use in many European and Asian schools while they are rarely found in any American text. (This is audio only)
