This site has been made by teachers that use technology daily to motivate and engage students in authentic learning, differentiate instruction, integrate many standards into one lesson and like to have FUN!:) It IS a work in progress. Please, please add ideas! 
Brainormous created by Aaron Turner, a flash script writer, is a web site with games for learning number facts. It focuses on third grade multiplication skills, using a solar system theme. Students go on missions to objects in the solar system and to get their fuel for each trip they need to do math facts. The faster and more correct they are they get more fuel. It also has addition and subtraction games that can be used at lower grades and of course for higher grade students who haven't mastered their addition, subtraction or multiplication facts. You can play free on line or download the software at a very low price. If you can it's always good to pay the creator for his/her time and effort to create these cool things for our students to use.
