GotKidsGames.com has some great language and phonics games for grades K-6 in it’s Word Games (http://www.gotkidsgames.com/GotKidsGames%20Word%20Games%20By%20Grade.html) area. The link to this area is currently at the bottom of the second column in the homepage. Some of the games keep score and some do not. There are plural, pronoun, subject-verb, adjective, and punctuation games to name a few of the ones that could be used in therapy.
Some of the games are short race the clock games to see how many correct answers can be done in a minute. I have found these most useful in therapy because they are quick, track data, and the kids enjoy them. 5 of these are subject-verb agreement games: 1st grade, 2nd grade, 3rd grade, 4th grade, and 5th Grade. There’s also a racing homophone and pronoun games. If you click on a few of the links in the last couple sentences you may notice some of the games have no ads. Playing around with this website, I noticed that you can change a few of the the .html ending to .swf and the ads go away. The .swf links a may eventually stop working, but I have enjoyed them the past few months.
Most of these games are flash games so they can work on Android tablets. It has come to my attention that the Android 4.1 and 4.2 no longer have official flash support, but you can still get it from adobe’s website in archives. I found a YouTube video that explains how to get flash in Android 4.2 (Jelly Bean). You can watch it below.
