SOME RUSSIAN MULTIPLICATION?


I'm learning a lot too! I never thought there could be such a nice way of multiplying. If you click on the picture you will see a large view of the image, with very clear instructions on how to do russian multiplication. We will do some more of http://www.hunkinsexperiments.com/ experiments. They look great.

RUSSIAN MULTIPLICATION


It is definetely a delight to see how much we can get from TeacherTube! This is a video that explains how Russian peasants used to multiply (and apparently some still do). You don't need to understand the whole video but simply understand the mechanics of the multiplication. You could find helpful to know the meaning of "even number (2, 4,...)", as opposed to "odd number (3, 5,...)". Try it out for yourself. Have fun.
