I created a shared map for the class. After the students had researched their country they would then access the shared Google map and add place markers for each of their countries. The final step would be to edit the place marker by adding the information they prepared. To help, I created a series of annotated images to walk them through the process. I have included the images they used below. The only thing I have not included here is the link to the shared map, but will add it once all of the students have had a chance to complete their portion of the map.
If you have questions or ideas, please feel free to add them in the comments below.
