Holiday Math Activity: Roasting a Thanksgiving Turkey November 1, 2015

Posted by Edward Deleon in : algebra, math, media , add a comment

Roasting a Turkey

Now that Thanksgiving is approaching, it’s time to start preparing for cooking a turkey. The USDA recommends cooking an unstuffed turkey or a stuffed turkey, according to these guidelines. These guidelines provide an excellent opportunity to explore graphs and equations of linear functions.

 

Unstuffed
4 to 8 pounds (breast) 1½ to 3¼ hours
8 to 12 pounds 2¾ to 3 hours
12 to 14 pounds 3 to 3¾ hours
14 to 18 pounds 3¾ to 4¼ hours
18 to 20 pounds 4¼ to 4½ hours
20 to 24 pounds 4½ to 5 hours

 

Stuffed
4 to 6 pounds (breast) Not usually applicable
6 to 8 pounds (breast) 2½ to 3½ hours
8 to 12 pounds 3 to 3½ hours
12 to 14 pounds 3½ to 4 hours
14 to 18 pounds 4 to 4¼ hours
18 to 20 pounds 4¼ to 4¾ hours
20 to 24 pounds 4¾ to 5¼ hours

 

Activity

For this activity, students can use a graphing calculator or software. Show students a prepared coordinate grid like the one shown here. They can use it to sketch out data and graphs and use the graphing calculator to test different scenarios.

Turkeygraphs1

Here is a link to a jpg version of this file. Right-click to download it.

Graph1

Have them graph the data from the table for the unstuffed turkey, like the one shown here.

Turkeygraphs2

Here is the downloadable version of this graph.

Graph2

Ask the following questions:

  1. Is there a linear function that could approximate the weight-vs.-baking time?
  2. Use your graphing calculator to find a possible function. What is the equation of the function that you found?
  3. Test the function against the data table. Does it give accurate results?
  4. Did you need to revise your function? What is the new equation?

Once students have worked with the data for the unstuffed turkey, have them work with the data for the stuffed turkey. The graph is shown here.
Turkeygraphs3
Here is the downloadable version of this graph.

Graph3

Repeat the previous set of questions with this graph.

Finally, combine both sets of data and include the functions. The combined data graphs are shown here.
