<p> Unit Lesson The Harlem Renaissance</p><p>Objective: Students will collect and organize data by using research through the Internet.</p><p>Activity: Students will research and fill in required information using the most recent year as the reference. Calculate the percentage of increase where required, then display the data. Information is given for 1920, but any year from 1920 – 1929 can be used.</p><p>A. 1920 data are provided. Find the data for last year: 1) U.S. President – Woodrow Wilson 2) U.S. Vice President – Thomas Marshall 3) Popular Songs – “Look for a Silver Lining” “Apple Blossom Time” 4) World Series Champions – Cleveland Indians 5) Heavyweight Boxing Champion – Jack Dempsey 6) U.S. Open Golf Champion – Edward Ray 7) Kentucky Derby Winner – Paul Jones 8) Hit Movie – “The Kid” w/ Charlie Chaplin</p><p>B. 1920 data is provided. Find the data for last year and calculate the percentage of increase.</p><p>9) Average Life Expectancy – 54.1 years 10) Dow Jones Average – 90 11) Loaf of Bread - .12 12) Gallon of Gasoline - .13 13) Silver per ounce - $1.09 14) Gallon of Milk - .67 15) Gold per ounce - $20.67 16) Average new car - $525 17) Average new home - $6,296 18) Average income - $2160</p><p>19) Is the percentage of increase the same for the loaf of bread and the gallon of milk? Circle: yes no</p><p>20a) If the answer is “yes”, construct a formula for the cost of the items write it as an algebraic expression.</p><p>20b) If the answer is “no”, write a separate expression for each item and graph both expression on the same coordinate axes and answer the questions in part C from the graph.</p><p>C. Answer the questions 21) According to the graph, what would have been the cost of these items in 1935, 1940, and 1950? Bread Milk</p><p> a) 1935 b) 1940 c) 1950</p><p>22) Suppose the actual prices of these two items for those years were given the chart below:</p><p> bread milk a) 1935 .08 .47 b) 1940 .08 .51 c) 1950 .14 .84</p><p>23a) Do the prices match the cost your graph predicted for those years? Circle: yes no</p><p>23b) If your answer is “no”, list some historical factors that may have changed the rate of increase.</p><p>Special Accommodation: Allow students to work in small groups. Complete some of the items as a class to serve as a model. Provide students with reference materials.</p><p>Dimension of learning: #2, #3, #4</p><p>Materials: Charts, paper</p><p>Assessment: Completed activity</p><p>Connections: Mathematics, Social Studies, and Language Arts</p>
