Game Goo is a site that says it provides “learning that sticks.” There are lots of reading games here, and they are organized by level. At the lower levels are phonics games focusing on sound discrimination, etc. My favorite game on the site is Monkey Business, a game where learners must arrange parts of a sentence to complete bridges for a monkey to cross. It would make a nice fluency activity for lower level learners. There is not too much vocabulary and much of it repeats. Fun and encourages speed. Flash-based.
