COMETS LESSON PLAN Working With Ratios Activity Area: Mathematics Developed by: Lori C. Niemann National Technical Institute for the Deaf Rochester, NY Target Audience: - Middle School Algebra Introduction: Students will participate in a game called "The Penny Box," calculating the ratio of events such as number of misses to the total number of pennies thrown. Students will then create equivalent proportions based on their ratios. Materials: Pennies Cardboard box 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.

44. 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

Ratios And Proportions GOAL: To accurately complete a variety of problems involving ratios and proportions. OBJECTIVES: The student will be able to: 1. Define the terms "ratio" and "proportion". 2. Derive the proper ratios and proportions from given descriptions. 3. Complete problems involving ratios and proportions. ENERGY OBJECTIVE: The student will be able to: 1. Discuss window and door placement on the home for maximum energy savings. LESSON / INFORMATION: 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? OR It is more accurate to express the ratio in lowest terms. If necessary, refer to the lesson on reducing fractions for the procedure:

**Written by Laura Grimwade, Rockdale County UbD (Understanding by Design) Lesson Plan Math (Geometry, 6 th Grade) Stage 1 – Desired Results 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: Students will understand that 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?

Lesson Plans Cycladic Figure It's All Proportional Lesson plan based on Cycladic Figure Skills and Focus: Measuring, Problem Solving Subject Area: Mathematics Thematic Connection: Counting and Calculating Grade Level: Middle School Time Needed: 60 minutes Objectives Instructional Materials Needed Cycladic figure Ruler, yard stick, or measuring tape Paper and pencils 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.

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.
