When I was a student I probably
asked the question why? too many times in a day. Sometimes, in math
especially, the teacher could give me the answer to that question and I would
still not understand (I’m looking at you, π, who decided what you
were?) But there is an important tool teachers have at their fingertips to
answer some of these questions.
- Why is a circle 360 degrees? Because
the Babylonians and other ancient cultures used a number system based on 60,
and degrees is left over from that mathematical tradition.
- Why does the Pythagorean Theorem work, and…who
was Pythagoras? Well, Pythagoras was a Greek mathematician, and his proof
using geometry proves this algebraic equation in a different way than showing
them the equation does.
- Why do we need math? There’s so many
historical answers to this question. Point to the computer scientists and
mathematicians that made it possible to go to the moon and have the computers
we have today. Point to any of the many discoveries that have allowed us to
advance as a society.
- Why do we have to do constructions?
Well, other than constructions are an important tool for students to understand
Geometry, point to the fact that mathematicians such as Euclid wrote entire
books talking about and using constructions hundreds of years ago, and those
books have been used and examined by mathematicians for centuries. It’s not
just teachers trying to make Geometry harder- its teachers showing students
where many of the rules in Geometry come from.
Combining
history and mathematics gives teachers a unique opportunity. You get to cross
disciplines (always a bonus!) and answer the students’ questions of why? It
gives teachers the opportunity to show that math is not a stagnant, boring
subject, but a subject that has been growing and changing for thousands of
years. Combining these subjects also gives teachers the opportunity to show
students that all their education is intertwined with each other. Showing
students this gives them an opportunity to have a more well-balanced and
well-rounded education. It allows students with strengths in different areas to
find a way to connect their interests with classes they may not enjoy quite as
much. If a teacher can show a student who loves history that mathematics is
connected to history, and put what they are learning in that context, they’ve
just opened a door for that student that may never have been opened.
Give that little background on Pythagoras at the beginning of class. Tell students about Babylonian number systems and about Hypatia and how she was killed for her work in mathematics. Cross the line that seems to divide subjects and give students the context that for some may connect ideas and bring a whole new understanding. And if it doesn’t help them understand the concept better, they’ve at least learned a fun fact, and one more fun fact never hurt anybody.
