Introduction
This web quest was designed as part of an assignment for Alliant International University
This lesson will be introduced on the second day of a Unity on similarity and proportionality. The purpose of the assignment is for students to apply the knowledge that they gain on day 1 of the Unit to investigate proportionality (and scaling). Through this investigation students will work with only 1 ratio (the golden ratio) and see how it applies to the natural world and to design. Through the production of a flyer, students will demonstrate their knowledge of ratios by using the golden ratio in their designs.
Learners
This lesson was designed for a “discovering geometry” class. These students have failed Geometry in the past and many of them lack basic algebra skills. The aim of the course is to expose students to geometric concepts while focusing on building their algebra skills.
Students need to know what ratios are and how to use ratios to create similar figures of different sizes. Students will need to know how to form an argument by making a claim and supporting this claim with evidence and sound reasoning.
Curriculum Standards
CCSS.MATH.CONTENT.6.RP.A.1
Understand the concept of a ratio and use ratio language to describe a ratio relationship between two quantities. For example, "The ratio of wings to beaks in the bird house at the zoo was 2:1, because for every 2 wings there was 1 beak." "For every vote candidate A received, candidate C received nearly three votes."
CCSS.MATH.CONTENT.6.RP.A.3.D
Use ratio reasoning to convert measurement units; manipulate and transform units appropriately when multiplying or dividing quantities.
Additionally, Students will present an argument in written form using evidence that they have gathered in their own research of the topic to support a claim.
Process
- Ratios and proportions exist in places other than your math book. First of all, let Mr. Benjamin tell you why he is excited about the Fibonacci numbers and the golden ratio at the link below

- Next, look through these websites to get a better idea of how the golden ratio and Fibonacci sequences are related to each other and to the world at large.

- Decide what topic you would like your flyer to focus on: nature, space, art, the concept of beauty, architecture, or any other suitable theme in which you can find examples of the golden ratio. These websites will help you find examples and pick a theme. Find 3 examples within your theme and include an explanation of each.

- Find an example of a misconception about the golden ratio (ideally one that fits your theme), and explain why this idea is inaccurate. Some of these have been mentioned in the links above, but the following links may also be helpful.

- Finally, design your leaflet layout with the golden ratio in mind (whether this means making the whole leaflet a golden rectangle, incorporating a golden spiral, using an “angle-a-tron” to make a flower with the golden ratio, or any other clever means). Make sure that your flyer includes an explanation of the golden ratio and an appeal to the public. This website may help you come up with some ideas. Include something that will grab people’s attention or spark their interest.

the biggest challenge that an instructor will face will be helping students to make design decision that will allow them to demonstrate their understanding of ratios. I anticipate that when students get to the last step they may have difficulty in deciding how to incorporate the golden ratio into their flyers. The best solution would be to have a short list of ideas that you can present to students and then encourage them to build upon them, or combine them, if this does not spur their creativity.
Resources Needed
Describe what's needed to implement this lesson. Some of the possibilities:
- Class sets of computers (lab setting would be ideal)
- E-mail accounts for all students
- Software: photoshop or other image editing software
- Class set of headphones
Given the large number of students working independently, it may be helpful to have an aid or a technical expert on hand who can help to resolve technical difficulties.
Evaluation
I will consider the lesson successful if the vast majority of students are able to make a flyer design that incorporates the golden ratio at whatever scale will be required for the flyer. As a secondary objective, students in this class have been learning how to form arguments (mathematical and semantic); I will be looking to see that they can construct and present and argument to the public.
finally, my students ask me every single day how what we are learning applies to the outside world, I hope this will give them just one more connection
