Apps for Kids

I recently went to an iPad training for my school district, and I learned so much!  We bought an iPad about 6 months ago, and Mary Scott loves it.  I have found lots of wonderful educational Apps for her that were FREE!  I was going to share some of these Apps because I know lots of people are looking.
Infants/Toddlers
Some are her favorite are interactive books.  They are not in the ibooks, but they are actual apps.  She loves the Wheels on the Bus, Old McDonald, and the ABC song.  The Wheels on the Bus is my favorite because you can listen to it is interactive when you click on things and you can record your own voice singing.  Mary Scott has loved these since she was a baby.
Bubbles- This was free, but I think it is .99 now.  This is a wonderful first app for a baby or a child with  special needs that is just learning cause and effect.  If you run your finger (or any body part) across the screen bubbles show up, and you can also pop the bubbles with your finger.  This is wonderful for isolating the index finger and for visual attention.
Kids Doodle (free)- another great first app.  This lets you draw with your finger, and you can change colors.
Toddler/Preschool
Counting Lite- this may be my favorite free app, and it is one of Mary Scott's favorite too.  The game puts pictures on the screen and you have to touch the picture as it counts the object.  It may have four dogs and you have to touch each dog as it counts, and then once you hit them all it will say 4 dogs, and then go automatically to another screen.  It teaches 1 to 1 correspondence, but I like that is very plain.  It has a white background and displays simple pictures.  There is an easy and hard setting, and the easy only displays objects up to 10, and the hard goes up to 20.
Starfall- This App cost 3.99, but it is well worth the money.  You can go to star fall.com on the computer, which is free, and you can get even more games and activities.  Starfall is used by most preschool and kindergarten teachers.  This game displays the alphabet, and the child can click on the letter, and it goes through a series of interactive screens that teach the letter and letter sound.
School Age
Fry Words (free)- This app teachers high frequency words through the use of flashcards.
Bill Atkinson Photocard- This app allows you to make your own postcard that you can email.  This is a great way to have kids practice writing without knowing they are working:)  You can use your own picture, or choose from gorgeous nature pictures.
Sightwords- Another app with sight words, but this one will test students, and will increase the number of options as the student answers correctly.
Addition Fun Lite- You can add from one to ten, and it will keep track of your score.

I am sure there are a million more apps, but this are the great ones that I have found.  I would love to hear if other people have good apps.
