Cheeky Panda is 2.5 years old now, here's her favorites apps:
Monkey Preschool Lunch Box (monkeypreschool.com)
Cost: $0.99 (Highly Recommended)
What the app do: It teaches the children shapes, colors, numbers, alphabets, matching, counting, problem solving and motors skill through little game tasks.
Why it works: Cheeky Panda has been playing with the game for 2 months. From the very first time, the colorful app with cute little monkey capture her attention right away. She tried to play with it all by herself since the beginning. With successful and fail attempts, she learned the shapes, colors, numbers and matching (which I tried so hard to teach her but failed) very well. Somehow she just figured out all these complicated concepts through the game herself without me explaining much. She can match and find the different object from a group easily now. At the same time, her motors skill and problem solving skills are clearly improved since she need to use her little fingers to drag and place some puzzle pieces to form some fruits' shape. Therefore, she is learning different kind of fruits also.
Monkey Math School Sunshine (http://monkeymathschool.com)
Cost: $0.99 (Highly Recommend)
What the app do: It teaches numbers, pattern, counting, concept of more or less and simple calculus (sum and minus)
Why it works: It shows the pattern along with narration, which have a blank in between, for the kids to pick 1 out of 3 objects to fill it. I found out the narration of the pattern actually help a lot for her to understand what is going on.
For counting and numbers, she has to connect the numbers dots from 1 -14 (more or less numbers) accordingly, so the turtle can cross the sea. She can count from 1 – 14 now, thanks to the turtle count along every dot he through.
There are four groups of sea creatures or objects to choose from, she has to pick the one with the most or the least.
. Sound weird but they actually are fun and help you burn calories. The main reason I switch to Kinect is no controller, you (the player) is the controller. I enjoy the Wii but really hate to exercise with two remotes on hand, who work out like that? The Kinect make much more sense, at least for exercise purpose.
and 
. They are both fun and sure keep your body moving. Dance Central is more fun to me because I like dancing to begin with. It has hit songs and cool moves in the game, started from a step by step tutorial, then you can perform it and even try a dance battle. Every song have different levels, you can build up your dance skills to your favorite tunes. I have to say they do have quite different moves in different levels which keep it fun.
