My second favorite I-Pad app is called Note Squish. It is a note reading tool and it is unique because of it uses groundhogs to interact with.
Letter names appear over animals who come out of the their holes. They must touch the right letter to match the note on the staff above. The groundhogs come and go and at times the correct letter is not on the screen so the student cannot guess by touching them all. The background music is fun and if it is annoying it can be muted.
I like the versatility in that I can choose which notes to drill and how many notes to drill,
This is the set-up page. Notice the speed can also be adjusted.
My students love it and it is small finger friendly.
