I would use this in a 5th and 6th grade class. The site real lives offers the chance to see how people in other countries live and act on a day to day basis. I would group the students into groups of 4 or 5. Each group would have to pick a country that they wished to live in. Then as a group they would have to create a project giving information on that country. Then show how this new learned inormation can bring something to our country. Finally they would have to live in that country for the duration of the unit in the real lives simulation. At the end of the project each group would give a presentation about what they learned. Students would be assessed on how well they interacted as a group and also would be assessed on their presentation of the material. I would use the simualtion to provide a first person account of every day life in the country they choose. This realtes to constructivist framework becasue the studnets are allowed to choose what country they want to lvie in. they are creating the base of knowledge they want to have.
