This was created for my higher level students to stay engaged while we covered fourth grade content. This allows students to use the internet to gather information about the height and country of various world landmarks. If you would prefer you can just print them the list of heights and go straight to the other activities. They then use that information to solve a series of math activities. There is one activity for place value, one for rounding, and one for adding and subtracting. In addition, there is a book for students to create in which they must locate and print a picture of each landmark and put them in order based on height of the landmark.
