Kids learn about things like manners, simple hygiene, recycling, seasons, safety, and more. The Elmo CD is perfect for younger preschoolers. My youngest child played this game a lot when she was first learning to use the mouse. Also, Elmo requests that you click twice to exit programs every time. Presumably, this is to avoid problems with kids accidentally leaving their games, but most preschoolers figure out what the stop sign means after a bit of trial and error.
Skills covered are adequate for a preschool title.
He's ticklish and fun and will bring your child back to the computer time and time again. The activities aren't bad either. You can't exit the program or activities very fast, but kids can still navigate the game quite easily. As noted above, it can be a bit slow. Difficulty levels are embedded in some of the directed activities, and adjust automatically.
