Measuring Lizards

A colleague of mine received an email titled “measuring lizards” with this study attached.  This blog post discusses the questions posed and further information about this interesting intersection of scientific inquiry and mathematical modeling.

Five Minutes of Fame: New Approach to PD

Teachers often struggle with finding the time to fit in professional development.  Even harder is finding actionable items that a teacher can incorporate into his or her classroom quickly and with mimimal cost and prepration time.  …

Why Do We Do What We Do?

Math is a Language.jpg

Today I want to talk about learning mathematics. Specifically, I want to discuss how we TEACH mathematics and why we do what we do.

This blog post was inspired by a radio broadcast by Science Friday titled “Does Math Matter?”.  You can listen below.

Graph Sense (aka Data Porn)


Today I want to talk about graphical representations. Specifically, I want to discuss some of the graph types that I’ve been teaching to my students in “Speaking with Numbers: Effective Use of Statistics”.  Feel free to contact me

More Maker Math


In today’s blog I will discuss how three “maker” projects can be tweaked to include more math. They could be tweaked further to make them into true STEM activities as well, but I will not go into that in detail in this blog.  Feel free to

Aviation Mathematics

Today’s blog comes straight out of the classroom.  My Aviation Mathematics I classroom, to be specific.  I want to share with you what happened when I “flipped the script” and began class with a problem that I asked students to solve

Calculus in Space

If you are a math teacher, you’ve probably heard the question, “When am I ever going to use this?” from your students, especially when you are challenging them to learn more complex mathematical topics such as Calculus.  Today’s blog post gives a lovely answer to that common inquiry.

Exploring Linear Equations Using Art


Guest Blog by Robin W. Ward

Today's blog describes a lesson in which the Wall Drawings of Sol LeWitt can be used to explore and discuss linear equations.  More about Dr. Ward’s and a link to her work is given below:

Dr. Ward, a two-time NASA fellow, also works as an educational consultant and presents workshops on integrating mathematics and the visual arts to educators, mathematicians, parents, and children. 

Dr. Ward’s Math Googles Facebook page.

Middle school algebra students recently donned their math goggles and engaged in a hands-on exploration of linear equations using the visual arts as a lens.

More Templates for Tetrahedra


Tetrahedron with Edge Lengths 3, 5, 7, 11, 13, 17

Guest Blog by Colin McAllister

Today's blog offers insight (and free templates!) on asymmetric tetrahedra.  It is the second post on this topic.  Here is the first. Mr. McAllister gives the following credit for the inspiration of this work:

Templates for Asymmetric Integer Tetrahedra


An Asymmetric Tetrahedron with Prime Numbered Edge Lengths

Guest Blog by Colin McAllister

Today's blog offers insight (and free templates!) on asymmetric tetrahedra.  Mr. McAllister gives the following credit for the inspiration of this work:

I was inspired to create these geometry templates by Dr. Diana S. Perdue's discussion “Request for applications on a math problem” in the LinkedIn group “Math, Math Education, Math Culture”.
I would also like to thank Dr. Linda Fahlberg-Stojanovska for advising that the templates would be useful for mathematics classes, and for suggesting improvements to their design. 

We are all familiar with the Regular Tetrahedron.
