How I Use It
I thought this app was a good introduction for grade school students. The free version is colorful and contains nice pictures of the UNESCO World Heritage Sites for students to try and match on the map. I liked the description of the World Heritage site which was available to students before they tried to place it on the map. I wish more of it was available for free but if a student really enjoyed it you can get all of the content for roughly $5.
I think grade school students would enjoy this app but I was a little disappointed in the way in which you place your guess on the map. It was difficult to get very detailed with your selection while using your finger on the app. A stylus would probably be a nice addition so that players could be more precise in their selection.
