Find Out About Fractions!


If you have half a mind to find out more about fractions, these sites will help you fill the other half!

There are sites with general information,
sites with lessons,
sites with lessons and fun on-line activities,
and some with just the on-line activities.

These sites are great for developing your knowledge of rational numbers and decimals,
and having fun with fractions!


 General Informational Sites (back)

  • Teachers interested in rational numbers and decimals might spend more than a small fraction of their planning time in a visit The Math Forum to find a variety of resources and links to fractions related sites. The site also contains a math topic search engine.
     

  • Is a question about fractions worrying you sick? Visit Dr. Math's site to find answers to all sorts of commonly asked questions.


Sites With Lessons (back) 

  • The Math League Multimedia site has quick explanations about how to add, subtract, multiply, divide, estimate and more with fractions. 


Sites with Lessons and Activities(back)

For a quick mini-lesson reviews of, and practice with, fractions, a visit to Visual Fractions allows you to do on-line activities in a extensive number and variety of fractions topics. For an explanation of the purpose of the site, see the information page. The table below will take you to specific activity areas.

The site also has a game called "Find Grampy" that involves naming fractions using a pictured number line as well as a harder version called "Find Grampy-Strict". Another game, "Cookies for Grampy", involves filling in a circle exacting by either clicking on pictures of the correct fraction, or typing it in. My fourth grade class doesn't cover multiplying and dividing fractions, but activities for these are also found at Visual Fractions.

*All the activities, for those with JAVA capable browsers, are designed for problem solving and further investigation usingArcytech's on-line manipulativepattern program.

  • Fun With Fractions provides a basic visual explanation of fractions, followed by a short multiple choice activity giving immediate feedback. Fractions-2 is a follow up page that involves simple adding of fractional parts, without requiring the reducing of fractions.
  • S.O.S. Math provides a number of fractions related pages including: Reducing Fractions; Building Fractions, which asks students to do the reverse of reducing; Adding Fractions; and SubtractingFractions. These pages are more detailed, and less visual, in their explanations and examples, but the related activities provide immediate answers, with explanations, and might be a good stop for students ready for a greater challenge.


Sites with On-line Activities(back)

  • Fresh Baked Fractions allows students to select difficulty levels in an activity requiring them to identify the equivalent fractions.
