As
I discussed in my last post the most obvious connection is the using bans in
the classroom and as a future math teacher I will be implementing a ban on
calculators except when I want to utilize them to help students visualize
graphs and relate them to concept and even then I am not sure if I will let
them use calculators or use computer programs or draw on the board or give them
models, which I provide. Students
will undoubtedly argue they will always have a calculator on them as phones now
work as basic calculators so why shouldn’t they have a calculator in class?
It’s not as if they’ll ever do basic math in real life anyways (LIES! LIES!
LIES! Basic math is a vital life skill!)?
The rationale behind my ban and how it relates to the soda ban is that
while it might not be a particularly popular rule it is, in my opinion, in
their best interest if they don’t become reliant on calculators so though my
students might not see it, I am indeed looking out for their best interests
just as Mayor Bloomberg is. In the
spirit of the numerous loopholes and ways to work around the New York soda ban
I suggested that I might allow abacuses, a 2000s BC calculator, and this still
holds true. Another potential
loophole is that some material will need a calculator for students to make
substantial improvements such as trigonometric functions in which case I will
need to ease up on my restrictions, but for less complex work the ban will hold
true (Muchas gracias to Pete for forcing me to recognize my oversimplification
of calculator usage!). Most

Reading
comments and opinion articles related to the ban it is evident that portion
size is a major issue in our culture and schooling is not preparing our youth
to understand portion sizes and make healthy decisions. Outside of health class, math might be
the subject most responsible for this lack of understanding. In geometry classes when discusses
3-dimensional objects I believe it would be useful for teachers to include not
only the usual objects like cones and cylinders but also food related objects
like cups, food packaging and portions.
The notion that increase a box’s size by 10% in each direction increases
the volume by 33.1% (1.1*1.1*1.1=1.331) is not intuitively evident to many
people. Pierre Chandon a French marketing
professor demonstrated how unaware most consumers are on the size of three
dimensional objects when he asked 294 people to estimate the size of three
different bottles and they routinely guessed wrong, underselling the volume by
20-40 percent (http://well.blogs.nytimes.com/2012/06/21/how-can-a-big-gulp-look-so-small/?ref=magazine).
Working with food in geometry to
better understand volume and 3-dimensional objects not only educates students
on portion sizes, but also can be more interesting and relatable to students
who might otherwise not see the importance of many geometry topics.Smorgasbord Fun Fact: Montpelier, Vermont is the only U.S. state capital without a McDonalds!
