The software is designed to accompany the Activity Books and Audio CDs. When children are very young, sitting at desks and looking at books can only be done for short periods of time. Children love to stand up, move about, release energy and get their whole bodies participating in activities. They love to play games, press buttons, hear noises and get instantaneous feedback. That is why the software is so important. It contains animated songs, chants and multiple games to consolidate learning. Minimum System requirements: PC - Windows XP and above. Mac OS X 10.6 and above. Internet connection required at installation.
