Reflection: Real World Applications Bubble Bubble Everywhere But Not a Drop to Drink - Section 1: Bellringer -Warm Up

 

Just a few days before teaching this lesson I remembered a video I filmed the year before for linear equations in two variables.  The video is based on proportional relationships found in retail.  I decided to use the video today as it is a throw back to 7th grade proportional reasoning and a clear connection to ratios.  I also knew my students would enjoy the change of pace by using a video instead of written bell ringer.   It turned into a wonderful review of content and vocabulary.  Here is a link to the video, my sister-in-low who filmed it put it on youtube.
