Parents, teachers and other educators have continuously sought ways to instruct children in a fun and interactive way. Counting games, alphabet blocks and activity books have long been staples of "fun learning," and these have been supplemented by educational technology. Software programs now teach children math, science, grammar, spelling, typing, and foreign languages. High school students can electronically practice for the SATs, while aspiring lawyers can find sample LSAT questions. Video games such as Math Blasters and Cyberchase allow children to explore fantastic worlds based on numbers and equations. The entire Encyclopedia Britannica appears in digital format, allowing for easy searches. Learning has never been easier, nor so enjoyable. Video games like this continually remind us that "Play is our brain's favorite way of learning."
