Con-SIGN-tration 4 is the fourth in a set of 4 game CD-ROMs that challenge reading and memory skills by requiring the player to match ASL pictures to English words that disappear if no match is made. Each CD game covers 10 different categories and related vocabulary. Two levels of challenge make the games appropriate for almost any age player. The games keep score of the number of clicks and matches and randomize every time they are played.

Con-SIGN-tration 4 covers the following categories: Politics, Religion, Home Sweet Home, House, Holidays, Careers, Family, Government, In the Kitchen, Food 2, and Food 3.
