How to Use the Golden Ratio in Design (with Examples) Want to be on the same creative level as Leonardo Da Vinci, Salvador Dali and the designers of the Parthenon? They all have one simple concept in common. The Ancient Greeks were one of the first to discover a way to harness the beautiful asymmetry found in plants, animals, insects and other natural structures. They expressed this mathematical phenomenon with the Greek letter phi, but today, we call it the golden ratio—also known as the divine proportion, the golden mean, and the golden section. Much like the rule of thirds, this mathematical concept can be applied to your graphic designs to make them more visually appealing to the viewer.
The golden ratio is a little more complicated, so we recommend you first read our guide to the rule of thirds if math isn’t your forte. What is the golden ratio? The golden ratio is probably best understood as the proportions 1:1.618. The Fibonacci sequence is easy to remember. Creating a golden rectangle Visualizing the golden ratio with other shapes.

This summer, which question will your kids be more likely answer ‘yes’ to? “Hey kids, do you want to help me bake some brownies?” Or: “Hey kids, do you want to practice your math skills so they don’t get too rusty this summer?”
I’m guessing that a whole lot more kids will jump at the chance to bake brownies over practicing math. But guess what? Now they don’t have to choose, nor will they want to, thanks to author and teacher, Ann McCallum, of Kensington, Maryland. McCallum and Illustrator Leeza Hernandez have found a clever way to turn math drudgery into deliciousness with their brand new book, Eat Your Math Homework: Recipes for Hungry Minds (see below for how to win a copy of the book.) McCallum explains, “When I first pondered how we could think beyond the ‘drill and kill’ of boring homework sheets, I was a teacher in a middle-class elementary school in Maryland.
McCallum shares her recipe for Tessellating Two-Color Brownies, below. Pin It A fun recipe with a lesson. Math in Daily Life -- Cooking by Numbers. Not all people are chefs, but we are all eaters. Most of us need to learn how to follow a recipe at some point. To create dishes with good flavor, consistency, and texture, the various ingredients must have a kind of relationship to one another. For instance, to make cookies that both look and taste like cookies, you need to make sure you use the right amount of each ingredient. Add too much flour and your cookies will be solid as rocks. Add too much salt and they'll taste terrible. Ratios: Relationships between quantities That ingredients have relationships to each other in a recipe is an important concept in cooking. 1/2 or 1:2 Both of these express the ratio of eggs to cups of flour: 1 to 2. Working with proportion All recipes are written to serve a certain number of people or yield a certain amount of food. Let's say you have a mouth-watering cookie recipe: This recipe will yield 3 dozen cookies.
Start by figuring out how much flour you will need if you want to make 9 dozen cookies. Project: Let’s Get Cooking. Let’s Get Cooking! Introduction Fractions are a large part of baking.

June 17 marks the first-ever World Tessellation Day, a holiday I created to bring awareness to the fun of finding and making tessellations.
Will you celebrate with us? Here are 10 great ways to play with tessellations, learn about them, and introduce your children to a math concept that opens a variety of creative learning opportunities. 1) Learn about tessellations with your kids. A tessellation is a tiled mosaic pattern of the same shape laid out over and over again, repeating into infinity. Tessellations can be found in nature, or they can be created by people.

Are you going to Staples or Target today? Take a walk around your neighborhood, looking for man-made tessellations. 3) Notice the tessellations in nature. 4) Explore an artist who works in tessellation.
One of the most famous was M.C. Search TES Resources. The Fibonacci number sequence has been astonishing and baffling mathematicians, nature lovers, scientists and the curious mind for ions. This number sequence was introduced by medieval, Italian, mathematician Leonardo of Pisa in his 1202 book, Liber Abaci (Book of Calculation). Along with the Hindu-Arabic numerals, which we use today (0 – 9), he introduced the east Indians use of the Fibonacci sequence through a famous problem about rabbit population growth. The sequence was named after him by number theorist Edouard Lucas in the 19th century. The number sequence is achieved by adding each of two subsequent numbers together to acquire the next number. It begins with 0 or 1, but the east Indians preferred to start with 1.
It goes like this: 1, 1, 2, 3, 5, 8, 13, 21, 34, 55 and into infinity! This rather remarkable sequence is found all over nature, but especially in the plant kingdom. Let’s not use 21st century technology with 19th century pedagogy. Technology may be changing but classrooms and teaching methods are pretty much unchanged since this picture was taken (Creative Commons image) By Larry Magid In a talk at the National PTA Conference in Charlotte, NC, Thomas Murray, State and District Digital Learning Policy and Advocacy Director for Alliance for Education, reminded me of what’s been bothering me for years. “We’re using 21st century tools in 20th century learning environments.”
I’d go even further than Murray. As far as I’m concerned too many of our teachers are using 21st century technology with 19th century pedagogy with teaching styles and classroom management techniques that haven’t changed much since my grandparents were in school. To reinforce his point, Murray showed pictures of typical secondary school classrooms taken in 1915 and 2015 and, in both cases, student desks were lined up in rows with the teacher at the front of the room.

Attack on the pentagon results in discovery of new mathematical tile | Science. In the world of mathematical tiling, news doesn’t come bigger than this. In the world of bathroom tiling – I bet they’re interested too. If you can cover a flat surface using only identical copies of the same shape leaving neither gaps nor overlaps, then that shape is said to tile the plane. Every triangle can tile the plane. Every four-sided shape can also tile the plane. Things get interesting with pentagons. The regular pentagon cannot tile the plane. The hunt to find and classify the pentagons that can tile the plane has been a century-long mathematical quest, begun by the German mathematician Karl Reinhardt, who in 1918 discovered five types of pentagon that do tile the plane.
(To clarify, he did not find five single pentagons. Most people assumed Reinhardt had the complete list until half a century later in 1968 when R. But then the hunt went cold. “We discovered the tile using using a computer to exhaustively search through a large but finite set of possibilities,” said Casey.

Fractals like these can seem too perfect to be true, but they occur in nature and plants all the time and are examples of math, physics, and natural selection at work! When we see order in the world, we think it must be some human hand that made it so. But Galileo Galilei in his Il Saggiatore wrote, “[The universe] is written in the language of mathematics, and its characters are triangles, circles, and other geometric figures.” There is order in nature, and artists who want to reproduce it faithfully spend hours studying nature’s forms. Civilization has struggled to understand this perfect geometry for thousands of years. Now you can join in the debate.

Using Google Apps in a Math Classroom. This week I am hosting some guest bloggers. This is a guest post from Bethany Mager. I have been teaching high school math for 12 years and I currently work to help teachers integrate technology in our 1:1 high school using Google Apps. I often find that math teachers are reluctant to use Google Docs in a math classroom, but Google Apps has completely transformed the way I teach. I will share some of my best practices and tips to get you started. Collaborative Challenge Problems The best part of using Google in the classroom is having students collaborate with each other on a document.
I often start a lesson with a challenge problem (that two students sitting together work on) a shared google doc. Doctopus is the best way to easily share Docs with student groups or pairs. Screenshots I love using online math tools in my classroom, including Desmos and GeoGebra. Images Of course, it’s true all math students must still do most of their work using pencil and paper.

Every evening around teatime, I have the joy of my son playing this game on the xbox with three of his friends from school. Now they don’t come round to play but meet up in a game world from the comfort of their own homes. As a regular listener to the verbal exchanges, I am fast growing to see educational potential in this piece of software.
