The research for this video comes from the article, “Three Balloons for Two Dollars” by Cynthia W. Langrall and Jane Swafford. The article can be found here: http://tidewaterteam.wm.edu/MPDCDocs/smpdfs/proportionareasoningmtms.pdf. How do the questions suggested in the video lead to the development of proportional reasoning? How is this different from teaching students to simply use a proportion to solve a problem? For the Mr. Tall, Mr. Short task, click here: http://tidewaterteam.wm.edu/MPDCDocs/smpdfs/TallTask.pdf.
