iPhone for Homeschoolers

I am the proud owner of an iPhone 3gs.  I know, I know, I am so behind on technology.  Probably most of you have had one for a while.  But since the new release of the iPhone4, the 3g and 3gs versions have really come down in price and we were finally able to afford a 3gs. (being a one income family, we have to fore-go some things and the latest in technology is most usually it.)  Anyway, I have been blown away by the wonderful educational apps that are available.  I've only had my new phone for 3 weeks, but I have already discovered many things that is helpful in teaching my daughter in a fun way at home, or when we need to fill some time in the car, at a restaurant or the doctors office.  The following is great for beginning math and word recognition.  It is called  "Teach me kindergarten."  Another App that I downloaded is "Sight Words".  This is 300 of the most frequently used words in the English language.  You can flag which words you want your child to study.  There are one letter, two letter, three letter and four letter words.  Also if you are just now teaching your child to tell time, I found a wonderful app called "Jungle Time".  It is a cute little animal face clock that starts with hourly increments and then goes to half hours and quarter hours when you tell it you are ready.  These are just a few that I have found really helpful with a kindergartner and I have seen many more apps for the more advanced student.  I can't wait to see what else there is to help me bring in some fun to our homeschool.
