Each fourth grade class had two chances to Mystery Skype with other classes in the United States. During Mystery Skype, our class video conferences with another class. The classes ask each other yes/no questions to determine the other class’s location. Students use logic to formulate questions and listen to answers carefully. One class was from California, one was from Iowa, and two were from North Carolina. We learned some new questioning ideas from the other classes and improved our own questioning. We loved it!
