43. AAM—The Renaissance Connection: Lesson Plans: Using Ratios proportion the relationship between two or more parts of a whole. ratio the relationship in quantity, amount, or size between two things. lesson plans. http://www.renaissanceconnection.org/lesson_math_ratios.html

Using Ratios Class: Math Theme(s): Background Leonardo Fibonacci was a Renaissance mathematician who generated a sequence of numbers that represent a "natural" order. The Fibonacci sequence is generated by adding the previous two numbers in the list together to form the next and so on and so on: 1, 1, 2, 3, 5, 8, 13, 21, 34, 55... The Fibonacci sequence can be found throughout nature. Look closely at a cauliflower and you'll see two spirals running in opposite directions. Count the number of florets in one of the spirals and you will find they follow the Fibonacci sequence. Divide any number in the Fibonacci sequence by the number before it, and the answer is always close to 1.61803. This is known as the Golden Ratio. Ratios are pairs of numbers used to make comparisons. Ratios can be written in different ways: 1 to 1.61803 or 1:1.61803, both meaning the same thing: the Golden Ratio. Like cauliflowers, snails too are touched by nature's golden ratio. Draw a rectangle in the proportions of the golden ratio, then draw consecutively smaller rectangles within it. Join diagonal corners with an arc. The result is a perfect snail shell. Giovanni Agostino da Lodi Adoration of the Shepherds About 1505 Oil on wood panel Enlarge Renaissance artists used the Golden Ratio to determine beautiful proportions in painting compositions. The proportion of land to sky in landscapes was figured using the Golden Ratio, and rectangular paintings were planned using the Golden Ratio to determine the sides of the rectangle: 1 to 1.61803. The composition of the

Literature Connection: poem " One Inch Tall " from the book Where the Sidewalk Ends by Shel Silverstein Mathematical Strand: Number Topic: Students will incorporate their conceptual understandings of proportions to write a creative piece similar to the example poem. Grade Level: Lesson Created by: Shelley Faerber, Susan B. Anthony Middle School, Manhattan, KS. Lesson Description: Materials: copy of the poem "One Inch Tall" by Shel Silverstein 1. Launching the lesson Read the poem/show copy on overhead or provide copy to students Discuss what would be encountered if we were all one inch tall in our classroom. What would be an obstacle? What would be fun to do? How would we use different items in the room? 2. Developing the lesson Brainstorm items in the room that are only one inch tall. Brainstorm items in the room/world that are approximately 64 inches tall? Now consider what items in the world might be 64 times taller than you? Your writing assignment today is to write a poem or paragraph where you describe what the sights, sounds, and surroundings of a specific area if you were either 1-inch tall or 64 times taller. You are either extremely small or extremely tall. Make sure your descriptions are true proportionally. RECAP: You have three very important decisions: 1)Are you small or tall 2) Where are you 3) What would you use and describe the surroundings?

Search the Site Investigations Number Concept Recommended Investigations In Ms. Matthews' classroom, there are 12 boys and 15 girls. In Mr. Lopez's classroom, there are 8 boys and 6 girls. In Ms. Waddell's classroom, there are 4 boys and 5 girls. Which two classrooms have the same boy-to-girl ratio? On one occasion Ms. Matthews' class joined Mr. Lopez's class. What was the resulting boy-to-girl ratio? On another occasion Ms. Waddell's class joined Mr. Lopez's class. What was the resulting boy-to-girl ratio? Are your answers to the two questions above equivalent? What does this tell you about adding ratios? Extensions Ms. Louvin's class has a boy-to-girl ratio of 5 to 6. At the end of the 1st, 2nd, and 3rd quarters, the class gets larger by two boys and one girl. So, by the end of the year, Ms. Louvin has 6 extra boys and 3 extra girls in her class since the beginning of the year. If the class never has more boys than girls, then what is Ms. Louvin's largest possible class size at the beginning of the year?

Lesson Plans Fallen Warrior Scaling Down Art Lesson plan based on Fallen Warrior Change the scale of a work of art using ratios, percentages, and proportions. Skills and Focus: Measuring, Calculation Subject Area: Mathematics Thematic Connection: Counting and Calculating Grade Level: Middle School Time Needed: 90 minutes Objectives Instructional Materials Needed Warrior Butcher paper Rulers or tape measures Pencils and markers Activity Step 1: Have students measure the printout of the Fallen Warrior. Explain that the size of the original sculpture is 21" high by 31" wide. Using ratios and proportions, have students convert the prior measurements to (a). life—size (dimensions of a real man), and (b). wall size (large enough to fill a portion of a classroom wall, so that the outline approximates the scale of a figure in a mural painting). Step 2: Using butcher paper, have students make outline drawings based on the printout in three different sizes: the original sculpture size (21" x 31"), life-size and the wall-size. The original sculpture panel was designed for the walls of a colonnade or courtyard. Have students discuss where the images of the two enlarged sizes might be, or could have been, displayed. Step 3 : Finally, tell students to use percentages as a means of comparing the different sizes of all four images (printout size, actual sculpture size, life-size, and wall size). For example, if the printout of the Fallen Warrior is 10 x 15 inches, then it is approximately 50% the size of the actual sculpture.

Materials Needed: None Teacher Instructions: The concept behind ratio is very simple. However, students seem to have serious difficulty, when they are in 8-9th grade, and they have to write ratios that involve variables to solve equations. Hence, special attention must be paid in 6-7th grades so that students clearly understand ratios. I suggest not even use the word ratio till they grasp the meaning behind ratio. Ask them if they know how to compare things. All of them will say, yes. Ask them questions such as: How much pizza is left, if you eat half the pizza? Normal response will be ½ Explain that when they answered the question, they actually compared amount of pizza eaten to the amount of pizza available.
