All of the educational computer activities were created or approved by certified school teachers and all educational games are free and are modeled from primary grade lessons and enhanced to provide an interactive way for children to learn. The grade level lessons incorporate areas such as math and language arts while introducing basic computer skills. Many of the kindergarten and first grade activities are equipped with sound to enhance understanding.
I have heard some say that they go up a grade level as well for a bit more challenging content for their kids.
Give it a try and let me know what you think!
