In a lively show, mathematician and magician Arthur Benjamin races a team of calculators to figure out 3-digit squares, solves another massive mental equation and guesses a few birthdays. How does he do it? He’ll tell you. (15:14)

Students will learn different strategies to determine the product of a multiplication problem. Skip counting on a number line, drawing a picture, drawing an array and writing a multiplication sentence are different strategies for finding the product.... User clicks through the slides.[more]

In this short video, students explain the process of factor multiplication. They use whiteboards to draw out the problem. This is a wonderful resource to introduce or to review this skill. Students will enjoy learning from other students (02:01)

The instructor offers a faster way to do two-digit multiplication than American students are traditionally taught, however, this faster method is known in Australian and British schools. The instructor uses a small, portable white board and two color...ed markers for his demonstration. (02:25)[more]

This video talks about how to multiply matrices using animation and a narrator. It lasts about three minutes and provides students with a clear example of how to do this operation.

What strategies can I use to solve a multiplication problem? This video shows the different strategies on how do to so by: repeated addition, make groups, multiplication table, skip counting, and arrays!

Introduction to Jakow Trachtenberg's math method called the Two-Finger Method (2FM). This strategy helps to gain control over numbers and also boosts concentration and memory. The instructor show the 4 rules of 2FM. Slide show with insert movie of... the presenter. Interesting strategy. (10:00)[more]

Trachtenberg's Two-Finger Math method is extended to multi-digit numbers in this slide show. The beginning of the video recaps part 1 and part two shows the steps to solving multi-digit multiplication problems using the 2FM Strategy. (09:18)

This video shows how to solve for the product of two numbers greater than five and less than ten using finger math. Examples are shown of the method for multiplying to single-digit factors on your hands and using pythabacus. Students need to know t...he 2,3,4,and 5 tables by heart to do this. (02:43)[more]
