# Longest NHL overtime games in history

Game one of the 2013 Stanley Cup between the Bruins and Blackhawks went into 3 overtimes.  People stayed up way too late to watch the conclusion.  The teams played 112 minutes and eight seconds of game time.  The game went from about 7:15 central time to midnight central time.  Did you know that Stanley Cup Playoff matches can last a really long time?There are usually few goals scored in hockey matches and a playoff match can not be finished as a tie. This has resulted in some very long NHL playoff  matches.

Engage your students with some authentic learning as they explore real NHL game data while using proportional reasoning.  Students learn about the length of the longest hockey matches in history and then try to determine how long it would have taken to watch them (TV time vs. game time).  Knowing that a regulation 60 minute NHL match takes around 2.5 hours to play, can students figure out how long it took to play out the longest games in NHL history?

Students will work with proportional reasoning along with some time conversions in this activity. As demonstrated in our solutions we encourage the use of ratio tables in this activity, which can be an intuitive way for students to solve ratio and proportion problems.  This activity is perfect for during the NHL season or during the Stanley Cup Playoffs.  Check out  and share the video below which highlights the longest ever modern day NHL playoff match.  Also, be sure to see if the Bruins and Blackhawks game one of the Stanley Cup falls in this top ten list of longest hockey games ever played and if the ratio of game minutes to TV minutes holds up to our 1:2.5 estimate.  Enjoy!
