ABCya

ABCya is a collection of educational games for grades K through 5th grade, created by and/or approved by licensed teachers. All of the games are free and are modeled from primary grade lessons for the purpose of providing interactive learning. The games have a strong emphasis on math or reading (or both) and all levels have the option for spoken directions. The selection of games and activities is extensive. And...they are fun! This is a collection of mainstream games; speed is not adjustable. The background music can be turned off if it is too distracting. All in all, there will be something for everyone here.
