## I'M TRYING TO LOVE MATH Expanding Mathematics Across the Curriculum

### Introduction

Mathematics is many things. For the youngest learners, math is counting and patterns. Math is shapes and calculations. Math is concrete and abstract. It can be used to plan and build a garden or to send astronauts into space. Mathematical concepts are steadfast but ever-changing. We use mathematics in shopping and computer science. It is a universal language that is learned and studied all over the world.

### Background Knowledge

It is generally believed that mathematics began with counting. A bone was found in the Democratic Republic of the Congo that shows notches that scientists believe were used for counting. From the Upper Paleolithic era, this Ishango Bone is thought to be 20,000 years old.

As civilization evolved and advanced, so did mathematics. For example, ancient Mesopotamians used stone counters in 3,000 BCE to represent quantities of grain and other goods. Other stone counters showed a base-60 number system and represented multiplication.

As the ancient world moved into the Bronze Age, Babylonians and Egyptians represented mathematics in a variety of ways. The Babylonians used clay tablets to record elements of geometry, including shapes and formulas, to calculate area. In tomb paintings, hieroglyphics and paintings show Egyptians engaged in calculations. The Rhind Papyrus contains numerous calculations and may have been used as a textbook for other scribes.

The great Greek scholars began learning more about mathematics between 500 and 200 BCE. During this time, some of the greatest minds explored mathematics and began to write about it. Pythagoras proved the Pythagorean Theory. Plato and Aristotle began to add mathematical concepts to their writings and teachings. Euclid, known as the "Father of Geometry," defined the axioms of geometry and proved many theories of geometry and number sense. Archimedes is considered the greatest mathematician of all time. He discovered concepts of calculus and furthered the studies of geometry.

The first known and documented female mathematician worked in about 400 CE. Hypatia lived in Alexandria and was a mathematician and scientist. She constructed but did not invent astrolabes and hydrometers used in astronomy. She is believed to have edited one of Ptolemy's writings. Her legacy is as a teacher and commentator in the field of mathematics.

Middle Eastern mathematicians dominated the following 600 - 800 years. Muhammad Al-Khwarizmi, of Persia, is known as the "Father of Algebra" and had the term "algorithm" named after him. Hasan Ibn al-Haytham studied the link between geometry and algebra. The Dresden Codex, the written Mayan number code, also came from this time.

In the 1200 and 1300s, Chinese mathematicians published many works. The Siyuan Yujian was four different titles and showed solutions for 288 individual math problems. Yang Hui wrote about what is widely known as Pascal's Triangle 300 years before Pascal in Europe. During this time, Leonardo Pisano, also known as Fibonacci, helped to bring Arabic numerals into wider use. He also observed patterns in nature that became the Fibonacci sequence.

From the Renaissance through the Enlightenment, great minds such as Leonardo DaVinci and Sir Issac Newton made advancements in mathematics. Modern mathematicians include Alan Turing, known as the "Father of Computer Science," and Julia Robinson, the first female president of the American Mathematical Society. Katherine Johnson, a Presidential Medal of Honor, worked at a segregated NASA and helped send American astronauts to space. Terence Taom was the youngest winner of the International Mathematics Olympiad at age 13. Modern mathematicians are creating mathematical theory as technology advances as well as proving and expanding upon existing mathematical theory.

• Zero, Zilch, Nada: Counting to None by Wendy Ulmer (ISBN 978-1585364619) - Harry starts his job at the balloon factory filling one hundred balloons for a party. With help from his friends, he practices counting by 10s, 5s, 2s, and 1s until he realizes he has no balloons left.
• Explore book lists that suggest titles for various strands of math, like this one from DREME out of Stanford.
• Read about the women who were pioneers in the field of mathematics:
• Engage students in a community of problem-solving with Math Circle activities. One key component of developing problem-solving skills is the act of reflection upon the activity. Use Flip (TeachersFirst review) as a tool for students to share and discuss their problem-solving process. Ask students to take advantage of the many camera features, including the whiteboard tool, to draw and share their thinking process.
• Learn about professions in mathematics and what mathematicians do with this resource from the American Mathematical Society. Encourage students to explore the field of mathematics further and share information on careers, important mathematicians, or fields of mathematics on a simple website created with Carrd (TeachersFirst review).
• Encourage students to analyze graphs and infographics with "What's Going On in This Graph?" from the New York Times. Have students use these graphs and infographics as a model for creating their own graphs for peers to analyze. Data GIF Maker (TeachersFirst review) is an easy to use graph creation tool for use by students of all ages. For more advanced students, Vizzlo (TeachersFirst review) offers many options for creating graphs and charts.
• Use a random Census at School data or poll your classmates to create graphs to analyze. Connect to the US Census and the math extensions provided. Use Create a Graph (TeachersFirst review) as an easy online tool.
• ### EXTENSIONS

• Pair mathematics with research as students learn more about famous mathematicians. Set brackets similar to the March Madness basketball tournament. Students present their mathematicians to their classmates and rank them against one another. Winners advance to determine the most influential mathematician of all time. Use this Free Bracket Generator to personalize and share your brackets.
