We have been taking out of the library for a couple months the Leapster Videos. My daughters love them and while it’s not the way we are teaching reading, it is definitely helping them with letter and sound recognition.
Amazon has them discounted. But with Amazon prices change throughout the day.
LeapFrog: Letter Factory for $8.27
LeapFrog: Talking Words Factory for $8.16
Another one that might help with basic math recognition.
LeapFrog: Numbers Ahoy for $8.95
