This Kahoot! involved 2 classrooms in Illinois, David’s own classroom in Glenview, IL, Theresa Allen’s classroom, a colleague from Juliet, and a 3rd classroom in Cape Town, South Africa.
If you wish to do as David and connect with other classrooms, a good way to do it is to use a screen sharing software, like appear.in or Google Hangout, that will allow one of the teachers to share his screen when launching the Kahoot! quiz and have all the classrooms see it and join in, independently of their location.
In the meantime, we leave you with some pictures that show how exciting the experience was!
