Big Burger

Mallie’sSportsGrillBurgerIn honor of International Hamburger Day (May 28, 2015), it's time to treat your students to ratios, proportions, fractions and BIG BURGERS! In this activity students explore the ratio of the various ingredients in the world's largest burger (pictured above & in the video below).

Students apply this ratio of ingredients to other "big burgers" and determine prices for these big burgers.  They also consider how long it would take their family to eat the entire world record holding burger (dividing by a fraction). This is a delicious math activity for exploring ratios, proportions and fractions with kids.

The activity focuses on the use of a ratio table. Give your students the opportunity to informally work their way to solutions using the ratio table.  Check out the videos about the "big burger" below.  Thank you to Robert Kaplinsky (check out his great math activities on his website) for letting us know about the videos from the History Channel.  Consider starting the activity with these videos.

Three teachers in Georgia created a version of this post that they felt was suitable for their 5th grade students.  Many thanks to Jenise Sexton, Michael Wiernicki, and Graham Fletcher for sharing their adaptation with all of us.
