Halloween-Themed Math Resources October 15, 2016

Posted by Edward Deleon in : algebra, geometry, Math , add a comment



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.

Lesson Sequence on Functions August 28, 2016

Posted by Edward Deleon in : algebra, graphing calculators , add a comment



We have produced a series of online lessons on the topic of functions. As a group, these lessons address the following Common Core standards:

We also have a teacher’s guide for this lesson sequence:
OER Resource: Teacher’s Guide for Functions Lesson Sequence

Here are the lessons:

OER Resource: What Is a Function?
OER Resource: What Are the Domain and Range?
OER Resource: What Is Function Notation?
OER Resource: What Does It Mean to Evaluate a Function?
OER Resource: Sequences and Functions

And here are some new lessons recently added:

OER Resource: Linear Function Models
OER Resource: Quadratic Function Models
OER Resource: Exponential Function Models


These lessons include instructional videos, as well as hands-on math through the use of an embedded Desmos graphing calculator.

Simply click on the links above and go directly to the lesson modules. You can also copy and paste these lesson URLs and include them in your assignments. Students do not need to log into anything. These free resources can be used any time and on any device.

Before you put that log in the fireplace, take a look at the logarithms involved in thawing frozen turkeys. In this issue of Media4Math we look at “thawing curves” using logarithmic models for thawing a frozen turkey.

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.


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


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



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.


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


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


Here is the downloadable version of this graph.


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.


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.

Holiday Math Activities: Halloween Approximation October 17, 2015

Here is a downloadable Word version, for easy printing. CandyCornMathActivity

During the holiday season, finding ways of weaving math into the festivities is an interesting challenge. There are many ways of doing this, and here is an approximation activity that should encourage your students to critically think about math. The image below can be printed as a transparency for use on a whiteboard or overhead projector.


Here are downloadable versions of this activity. Simply right-click on the link and download the file.
