I would like to find a school in South or Central America that has Spanish speaking students who are just learning English partnering with our High School Spanish class. Each teacher could have their students interact. The instructional activity that comes to mind now is having each group give directions to the other class in the language being learned. Assessment can be done by comparing how well the other group followed the instructions. A game of 20 questions would work well for this too.
