Lesson Objective
The Ratio that Tops them All
- What will students discover
- Students will discover the Golden Ratio and then we will use technology to explore different areas that it appears through the use of applets
- How will they discover it?
- Students will find ratios for familiar items, as well as unfamiliar ones, to discover the “Golden Ratio” of Mathematics.
- How will you measure their understanding? (Use measurable verbs.)
- I will ask them high cognitive demand questions throughout the lesson, as well as observe their group work. There should be not only algebra worked out, but also pictures of their thinking.
Use the above to help you write the Content Objective.
Students will be able to analyze data about geometric shapes and discover the Golden Ratio by manipulating figures & comparing their lengths with applets and demonstrate this knowledge by sharing ideas out loud in groups where they will have not only algebra, but also pictures to reason their findings.
Materials Used (be specific):
Paper, writing utensil, chart handout, document camera, ruler, measuring tape, images for historical content, computers for students, access to math applets about the Golden Ratio & Fibonacci numbers
Classroom Management (how will you get the attention of the class?; pass out and collect supplies?; will students be working with a partner? in groups? when?):
I will let students know, at the start of class, which techniques I will be using, such as a countdown timer on the board, clap once to get everyone’s attention, individual vs. group work vs. class work. Knowing when to listen and when to share ideas. To keep track of time, I will project a timer on the board during group or individual work so that students can see how much longer they have to work, as well as the buzzer will go off and that will get their attention. If an activity is not being timed, then gauge how much more time students need and proceed as necessary.
| ENGAGE: Connect to Prior Knowledge and Experience, Create Emotionally Safe Learning Environment, Excite Students about Today’s Learning Objective Estimated time: 5 minutes Description of Engage: The students will be shown a picture of da Vinci’s Vitruvian Man and asked what they know about it. |

| Show students the image of the Vitruvian Man. Ask them what they know about it. See what their prior knowledge consists of and build on what the students share. Share where da Vinci’s motivation came from for this picture. This goes along with notes based on the work of the architect Vitruvius. Ratios discussed.
The drawing, which is in pen and ink on paper, depicts a male figure in two superimposed positions with his arms and legs apart and simultaneously inscribed in a circle and square. Called Proportions of Man and is only displayed to the public occasionally. Vitruvius determined that the ideal body should be 8 heads high.
|
Have we seen this before? |
Yes, on TV. The circle has equal radius all the way around, so the distances are the same. |
| EXPLORE: Hands-On Learning, Contextualize Language, Use of Scaffolding (Graphic Organizers, Thinking Maps, Cooperative Learning), Use of Multiple Intelligences, Check for Understanding Estimated time: 20 minutes Description of Explore: Students will be given a worksheet and various objects to measure. |

| Give instructions about the task. Do not yet pass out materials (they will get distracted). Model the first measurement, reminding students that a must be greater than b when they document it on their table. Keep in mind to the nearest tenth. -Big ideas person (pulls group back to focus) -Clarifier (monitors concept comprehension, measure lengths) -Explainer (measures group progress, records information) -Peacekeeper (controls the floor) EVERYONE: questioner |
Why are you measuring that part? |
We only need the height and width/we might need the diameter and circumference/etc. |
| EXPLAIN: Listening, Speaking, Reading, and Writing to Communicate Conceptual Understanding, Define Vocabulary Estimated time: 10 minutes Description of Explain: Students will explain their method of finding a pattern in groups and share in a whole class discussion, then see a short video about a few different appearances of the Golden Ratio. |

| Let students Think-Write-Pair-Share about their findings. Then when we bring it to the whole class conversation, everyone will already have their thoughts written down. Implementing this strategy is good for ELL or students with special needs because it allows them to write down and rehearse their thoughts so they do not feel uncomfortable when speaking in front of the class. http://www.mathsisfun.com/numbers/golden-ratio.html |
Where are you starting? |
We took the circumference and divided it by the diameter, which gives us pi. Some of them use shapes, others lines or area and another used a human, which is more easier to understand in person. |
| EVALUATE: Thinking Maps, Summarize Lesson and Review Vocabulary, Variety of Assessment Tools, Games to Show Understanding, Test Students on the Learning Objective Estimated time: Done throughout Description of Evaluate: Listen to student responses and press their thinking for mastery of material. |

| Teacher’s Role | Teacher Questions | Students’ Role & Answers to Teacher Questions |
| Teacher will evaluate students throughout the entire process, ranging from class discussion, to group discussion, to individual work, to conversations heard around the room. What are you still confused about? What are you curious about? |
Why do you think this happens? |
These look like they have similar proportions. |
| EXTEND/ELABORATE: Group Projects, Plays, Murals, Songs, Connections to Real World, Connections to Other Curricular Areas Estimated Time: 5 minutes Description of Extend/Elaborate: Show students a video and tell them to find other shapes at home to measure and see which one is closest to the Golden Ratio. |
||
| Teacher’s Role | Teacher Questions | Students’ Role & Answers to Teacher Questions |
| Give instructions about finding 5-10 items at home to measure and see how close they can get to finding the Golden Ratio. Bring them to class tomorrow and we will see who gets the closest! |
What do we think will give us the best ratio? Now we know what the number is, make a conjecture in your math journal about which items you want to measure and which ones you think will have the closest match to the Golden Ratio. |
Yes, I’m going to try the television. |
I noticed that you said they would use an applet to determine the golden ratio, but I didn't see an exact applet that you were planning on using. It would be difficult, as a teacher reading your blog, to be able to carry out this lesson, if we don't know where to find it, and where exactly it will be incorporated.
ReplyDeleteHi Kathryn! One thing I really like about this lesson is that it isn't purely computational, and is not a traditional lecture then individual work-time structure. I love the integration of history and culture. I did not actually see too much of the applet being utilized in the lesson, but I can definitely see where it can be. For instance, I am sure there are statistical applets where students can input data and see how they vary from each other or may follow some type of function or patter. That would be really great for students to visually see their data plotted out like that. The idea of letting them explore applets as an extension to the lesson is also great. Especially if the students seemed very intrigued by the topic of the lesson, it would be handy for them to be able to go home and explore the topic some more on their own. Overall, great lesson that I would consider conducting in my own classroom :).
