Altissima's Trachtenberg Multiplication Tutorial
You can visit our Trachtenberg Tutorial website and download a free copy of Trachtenberg Multiplication for your Math Lab.
Our tutorial teaches the alternative method of multiplication published in "The Trachtenberg System of Basic Mathematics" and is fun for the gifted student as well as helpful to those who would benefit from an interesting way to learn about multiplication other than simple memorization.
When your students ask "How does it work?", you can explain that the keys to understanding systems like these are found in Algebra.
