Mathematicians Write Picture Books!

You may have noticed a new bulletin board in the math wing at Medfield High School.  
Although it’s content is short and sweet...and the papers are somewhat crooked...
the message behind it is hopefully powerful.  


In math, we aim to provide students with a framework as they explore and make sense of
the world around them.  Teachers ask students to look at relationships through 4 lenses:

Numerical Verbal Visual Algebraic

Although the level of abstractness, complexity and scope varies as students move up in grades,
this framework never changes. In essences this a framework  to be considered when choosing
learning strategies.  My students and I discuss this often in Algebra II as we look to try out new
strategies for learning math. One of my favorite learning strategy is referred to as Dual Coding.  
I have included an article by Jennifer Gonzalez,
6 Powerful Learning Strategies You MUST Share with Students in Cult of Pedagogy.  
She concisely explains...

“The idea (of dual coding) is that by combining a visual representation of an idea
with a verbal representation of an idea, we will be able to learn the idea better.”

True to the strategy, there are many pictures available in this post to help students and teachers
understand Dual Coding as a learning strategy.


So why have a picture book at the center of our math bulletin board?  Not only does it provide
a great story of diverse mathematicians, but it is a reminder of the value of pictures in math.  
In Algebra II we settled on this notion: if mathematicians were authors, they would be authors
of picture books or graphic novels.  We would never want to explain the patterns we come upon
with only words and numbers. We always want pictures to help us illustrate everything we see.  
What better way than to celebrate some fabulous books of our childhood?

My hope is this bulletin board can travel to your school. (Link included here for content.)
We are even  happy to mail you our copy of the book, Hidden Figures: The True Story of Four
Black Women and the Space Race, by Margot Lee Shetterly (Author), Laura Freeman (Illustrator),
as long as you are willing to ‘pay it forward’ and send it to another school:-) Thank you!

Hello, Mathematicians!

When I write emails to students and their families, I have started using the salutation,
“Hello, Mathematicians and Families of Mathematicians!”  I now do this every time.  Every single
time.  It may sound simple, but I do this for 3 reasons.  First, it is sounds very friendly...and
that is what I am going for:-)  Second, I am addressing mathematicians as well as their families,
so I am interested in being very accurate with my words...we math teachers tend toward precision.
Third, it is a signal to the students, their families and myself that I am the teacher of
mathematicians.  I am the teacher of 24 mathematicians that are able to see things in different
ways, have a wide variety of experiences and lots of diverse strengths, all of which they bring to
the table when studying math.  


My friends who are math teachers...and I have a lot of them at Medfield Public Schools...all agree
on one thing:  Mathematics is about patterns.  Somehow, we gain happiness from noticing patterns,
especially if they involved numbers.  I discovered a math teacher on Twitter over the summer:
Sara Van Der Werf.  She writes in her blog that part of her speech to her students on the first
day of math class involves saying the following:

“The first thing mathematicians do is notice patterns...
Everyone has the ability to notice patterns.  Everybody...
The 2nd thing mathematicians do is describe patterns...
You can describe it any way that makes sense to you....
The 3rd thing mathematicians do is to generalize patterns...
Mathematicians notice, describe and generalize.”

Well, Sara, I couldn’t agree more.  Our #MedfieldMath students notice patterns, describe
patterns and generalize patterns every day in math class.  Their work is amazing and they are all
mathematicians!
