Extractions: February Project Timeline Week 1 Week 3 Week 4 ... Week 5 Objectives Monday 9 Homework Solve Proportions. Use proportions to solve real-life problems. QCC: 1, 28 Ratio and Proportion Warm - up (10 min) - The students will work on problems written on the overhead projector for review or remediation. Activity - (35 min) - The students will be introduced to similarity and ratio and proportions by examining various web sites that involve architecture and design. They will then be given measuring tape and told the length of the Statue of Liberty's nose and asked to find the length of her arm using the measuring tape and a pencil. They will work in groups to do this. We will put the results in the graphing calculator to graph a box-and-whiskers plot. We will do a statistical analysis and compare the results to the real value. Closure - (15 min) - The students will present their findings to generate a class discussion. Solve problems written on the board.
NCTM Lesson Plan mathematics Overview In this lesson, students use real methods for solving problems involving proportions, such as scaling and finding equivalent ratios. http://illuminations.nctm.org/lessonplans/6-8/rationalnumbers/

AAMThe 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
Extractions: 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. 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

Extractions: 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?
Cleopatra lesson plan based on Fallen Warrior. Change the scale of a work of art using ratios, percentages, and proportions. Skills and Focus Measuring, Calculation. http://www.artic.edu/cleo/Teachfolder/WarriorHTML/FINAL/Warrior.Math.2.html
Extractions: 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.
Cleopatra It s All Proportional. lesson plan based on Cycladic Figure. Objectives. Practice measuring proportions. Convert measurements to ratios to solve problems. http://www.artic.edu/cleo/Teachfolder/Cyclhtml/FINAL/Cycl.Math.2.html
Extractions: Activity: Step 1: Explain to students that according to the Greek canon of proportion, the length of the body is equal to 8 heads (1:8). Have each student measure the head and the entire length of the figure and record the information. Then have students calculate the length of the body using the 1:8 ratio. Step 2 : Have students determine whether there is enough information to calculate the length of the lower legs and then do so. Ask students to sketch the lower legs and feet on the printout of the figure to confirm their findings. Step 3 Goals This activity meets Illinois State Goal Demonstrate and apply a knowledge and sense of numbers, including basic arithmetic operations, number patterns, ratios, and proportions. This activity meets Illinois State Goal 8: Use algebraic and analytical methods to identify and describe patterns and relationships in data, solve problems, and predict results.

Ratios And Proportions You may have to refer to your notes from the lesson on measurements. 2. Find these ratios. 4. How can proportions be used to solve math problems? http://www.leeric.lsu.edu/bgbb/7/ecep/math/q/q.htm
Extractions: Ratios are simply comparisons among quantities of the same kind. Ratios can be helpful in solving a variety of mathematical problems. An example of a ratio might be 1:4. Ratios are a usually written in this format; however, they may also be written as a fraction, such as 1/4. The ratio is read as "one to four". How are ratios derived? Remember, a ratio is simply a comparison between two like quantities. See Example 1. Example 1: A home has 2400 square feet of living space. The home also has 400 square feet of glassed window area. What is the ratio of glassed area to total square footage?
