Decomposing Fractions

We have begun our fractions unit, and one of the first skills we are learning about is how to decompose a fraction.  Until recently, “decompose” was a word that I applied to science–not math!  “Decompose” means to break down or break apart into smaller parts, and I’ve learned that we can apply that word in math, too!  Parents–we did learn this in school, BUT–we just didn’t use the same vocabulary.  Below are a couple of sites that provide the students with practice decomposing fractions.  The Khan Academy site also has a video included on the right side in case the students (or the parents) want to know more about the skill.  🙂  Just click on the picture and that will take you directly to the practice.

Virtual Fraction Manipulatives

We have been working on finding equivalent fractions and comparing fractions in math.  Some of the manipulatives that we use in class are pattern blocks and fraction tiles.  The picture below will take you to a website where the kids can use fraction tiles and circles to make all kinds of discoveries such as equivalent fractions, adding/ subtracting fractions, modeling & identifying improper fractions & mixed numbers, and comparing & ordering fractions.  Not only can the fraction pieces on the site be moved or manipulated, but there is also a work space with a drawing tool that the kids can use to write the equations or fractions that they’ve modeled.  They can then take a picture of their work and email it, or even post it on their blog!  It is also a wonderful resource to use when working on fraction homework!  To check it out, click on the picture of the fraction tiles below.
