This free math video shows a great activity to do with two or more children once they understand a few basics about fractions (shown in the previous video). They will discover fraction rules on their own!

Children should do this activity many times with various rods used as “one” or the “whole.” This will help them internalize and generalize the concepts they are learning.

Cuisenaire Rods are a kinesthetic and visual way for children to play with numbers.

How to go from an understanding of 1/2 to knowing how to do 3/5 x 10. It’s not hard with Cuisenaire Rods! The trick is to use the word “of” when reading the multiplication symbol. Everything becomes clear!

I learned this from the Miquon math curriculum. It is a WONDERFUL program that uses Cuisenaire Rods to teach concepts and it is extremely inexpensive – totally worth it to try at home with your K-4th grade children! If I could only choose one math program to use with my kids, this would be the one!

This free math video shows me introducing fractions with Cuisenaire Rods to a friend of my daughters. It’s pretty easy to see that oftentimes the child leads the way in the discussion, sometimes rushing ahead of you and sometimes needing more time to digest the concepts.

The most difficult part of doing fractions this way is changing the names of the rods, calling something other than the white rod “one.” Therefore, this activity should be done many times with different rods named as “one” before trying to introduce more complex concepts. Having the ability to rename any rod as “one” or the “whole” makes adding and subtracting fractions later on very easy because children can switch back and forth between regular multiplication with the rods (where white is “one” in order to find the LCM) back to thinking in terms of fractional parts of whatever rod length is the denominator. And it makes it easier for them to know which rods to grab if, for instance, they want to find 7/8 of the orange-orange-purple (24) rod.
