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.
Check out the full collection!

CCSS.MATH.CONTENT.HSF.IF.A.1
CCSS.MATH.CONTENT.HSF.IF.A.2
CCSS.MATH.CONTENT.HSF.IF.A.3
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.

Holiday Math Activity: Roasting a Thanksgiving Turkey November 1, 2015
Posted by Edward Deleon in : algebra, math, media , add a commentRoasting 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.
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:
- Is there a linear function that could approximate the weight-vs.-baking time?
- Use your graphing calculator to find a possible function. What is the equation of the function that you found?
- Test the function against the data table. Does it give accurate results?
- 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
Posted by Edward Deleon in : algebra, geometry , 2commentsHere 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.
Teaching Tips
- The purpose of this activity is for students to focus on problem solving and process. The number of candy corns that fit inside an empty Smart Car is less important than the process for finding the answer. Encourage students to think creatively and mathematically.
- Reinforce to students that although this is an estimation activity, it is primarily a problem solving activity. Encourage students to use problem solving strategies to develop a plan.
- Have students work in groups that include a diverse set of learning styles. Visual learners, tactile learners, and learners that are adept at technology can work together to brainstorm a clever solution to the problem.
- Have a supply of candy corns, volume measurement tools, rulers, calculators, papers, pencils, colored markers and whiteboard available for students to work in groups. If possible bring a scale model of a Smart Car.
- Have students put together a coherent presentation showing their methodology and results. Their presentations can be done in PowerPoint or simply on a sheet of poster paper. Let each team decide.
