HalloweenMathActivities

 

Media4Math has created a collection of math resources that are Halloween themed. This collection includes games, interactives, presentations, and more. To see the complete collection, go here.

Start with our Pumpkin π activity: http://www.media4mathplus.com/SlideShow/231/Pumpkin-Pi. In this multi-grade activity students measure the diameter and circumference of different sized pumpkins, create a scatterplot, estimate the line of best fit, and determine the slope of the line. This hands-on activity is a great way to explore the concept of π, while weaving in other concepts.

Or try our whack-a-mole games. This suite of games test divisibility rules. Depending on the game, students are either “whacking” pumpkins or bats with numbers on them. Students gain points when they identify the correct divisibility rules, but they lose two points when they choose the wrong number.

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

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.

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.

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.

Slide01.jpg

In the current issue of Math in the News we look at data around the price of gasoline and oil production. We analyze graphs and look for functional relationships among the data sets. This is a great opportunity to bring a timely, real-world connection into your classroom.
This slide show includes an embedded GoogleDoc with all the data, which you can then copy and paste into a spreadsheet or graphing calculator to create your own graphs.
