Checking for Understanding with Today's Meet

Mrs. Pazos' World Cultures Classes recently used Today's Meet, a free back channel website, to demonstrate understanding of longitude and latitude.  Mrs. Pazos would give the students latitude and longitude coordinates and the students would have to look on their map and put what continent was located on those coordinates.  Mrs. Pazos said, "I like that I can see if a student is getting the answer wrong and then I can check in with him/her.  Polleverywhere does not show a name.  They feel like they are getting to do something super fun on the computer...but really they are learning latitude and longitude!"  What a great way to quickly check for understanding.
