Apps & More | PBS KIDS Mobile Downloads | PBS KIDS pbskids.org is a website full of school-related activities to enhance children's thinking. The children can play with their favorite PBS character. There are apps, too. This can be used at home, as well. Phonics, math, words, and everyday skills are worked on. To add, I would use the writing contest app on here to encourage writing.
PBS KIDS Super Vision App | Designed specifically for parents, the PBS KIDS Super Vision™ app helps you monitor and make the most of what your child is learning and playing on pbskids.org. (Available for iPhone & iPod Touch)
