Extractions: Rates and Proportions Submitted By Dale Kelly School/District I.S.232, Brooklyn, NY Overview This lesson will help students better understand and apply concepts related to ratios and proportions. ( NOTE: This lesson can be used for a pre- or post-simulation activity.) Simulation and Episode RioTech Solutions Episode #2: Rockin the Web Subject Area Mathematics Suggested Grade Levels Middle School Time Allowance One class period Concepts/Objectives Students will be able to: Compute accurately with arithmetic operations on rational numbers. Use rates and ratios to express part-to-part and part-to-whole relationships. Reason proportionally to solve problems involving equivalent fractions and ratios. Resources/Materials Activities/Procedures Warm-up : Ask students to represent the make-up of the class as a ratio of girls to boys. Make sure students remember to use a colon in their representations (i.e., 10:15)

Extractions: Hands on Activity: Introduce the formal definition of Ratio to the students. A Ratio is a comparison of two measurements. Students are to take turns tossing 10 pennies towards the center of the cardboard box provided by the teacher. Using the worksheet provided, students should be recording the misses and successes of each other. When everyone is finished, students are then to calculate the ratio of hits to total shots. On a second worksheet, students are to choose two of the students in class and predict using their information, how many hits would be made if there were 20 shots taken, 50 shots, or 100 shots. Discuss with students their predictions and reasons. Explain the definition of a proportion. Demonstrate how to use a proportion to solve a problem like the above predictions that does not include guessing.
Ratios And Proportions Derive the proper ratios and proportions from given descriptions. lesson /INFORMATION ratios are simply comparisons among quantities of the same kind 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?
UbD UbD (Understanding by Design) lesson Plan. Math (Geometry, 6th Grade) Students will use ratios, proportions and different scales to determine drawing http://www.intermath-uga.gatech.edu/lesson/symmetry_lesson.htm
Extractions: UbD (Understanding by Design) Lesson Plan Math (Geometry, 6 th Grade) Established Goals: (M6G1) Students will further develop their understanding of plane figures. (M6P1) Using appropriate technology, students will solve problems that arise in mathematics and in other contexts. (M6P5) Students will create and use pictures, manipulatives, models, and symbols to organize mathematical ideas. Understandings: objects may or may not have line and/or rotational symmetry. scale drawings are related to real-world similar plane objects that are large or small. scale provides a mechanism by which we can solve problems related to large or small real-world objects. Essential Questions: Why is it important to understand symmetry? Why are plane figures important in the real world? How are scale drawings related to similar plane figures? How can you represent a large image in a smaller proportion? To what extent do professionals use scale to analyze real-world extremely large or microscopic objects?

Cleopatra lesson plan based on Cycladic Figure Practice measuring proportions. Convertmeasurements 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.
Cleopatra lesson plan based on Fallen Warrior Using ratios and proportions, have studentsconvert the prior measurements to (a). lifesize (dimensions of a real 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.

Extractions: This is an interactive, media enhanced lesson that requires students to examine ratios and proportions. The primary goal is to develop connections between math and real-world situations. Through the use of video, students will explore a relevant application of ratios and proportions. Using the internet, students will apply this concept through guided practice and interactive feedback. Students will then make connections to other real-world examples by applying this knowledge to similar problems in other areas. This lesson incorporates mathematical skills, reading, and writing in an interdisciplinary format. Learning Objectives:
