Vocabulary Practice. Lots of fun games to help you learn lots of new words! http://www.vocabulary.co.il/
This web site has a lot of fraction games that play like real video games. They want you to think fast and be clever. I spent a lot of time enjoying myself at this site. IMPORTANT: When you click on a game it will ask you to register. Don't Register. There is no reason to, and you will just get on some email list. Click on the button that says "Maybe Later" and just play the games. http://www.iknowthat.com/com/L3?Area=FractionGame&COOK=
This site is called FUN BRAIN and it is FUN! It is a great game that teaches Equivalent Fractions. You can set the game from Easy to Super Duper Hard. Have a good time with this one! http://www.funbrain.com/fract/index.html
A really good site for practicing all types of math. I have given you the address for the fraction section. Scroll down to Beginning Fractions, Equivalent Fractions or Converting Fractions and click. Once you get to the right page scroll down for some great practice. When we get to other fraction functions, you will be able to use this page again. http://www.aaamath.com/fra.html#topic15
