The Winter Olympics in Sochi, Russia provide a once, every 4 year, opportunity to learn about the Winter Olympic sports and Olympic champions. This scavenger hunt is a great way to acquaint your students with the winter sports events in the Olympics. It will also teach them a little about the host country.
Also, check out the classroom Olympic Challenges I have in my store. Your students will use their creativity to transform ordinary materials into winter sports equipment for classroom competitions. (Olympic Curling Challenge, Olympic Bobsledding Challenge, Olympic Ski Jumping Challenge)
