I use this app when my 2nd Grade class "travels" to China and they love it. Great visuals, traditional story, and many ways to explore Chinese culture. We also love The Dream about Egypt. You should make similar apps based on other countries (Mexico, India, Brazil, Russia, South Africa, Italy...)!

I love how this app is so student-friendly and it makes the connection between numbers on a clock and numbers on a number line. The only problem is on the analog clock, the numbers appear on top of each other. For instance, 12, 1, and 2 are all stacked on top of each other so when it asks for the missing number, there is no way to know the answer. That's the only bug I see needs to be fixed. Thanks!
