**Plan of Action** **Goal** Increase middle school math teachers’ use of the library media center by developing collaborative lesson plans. **Lesson** Population Statistics Grade 8 2 class sessions *adapted from the Tennessee Electronic Library lesson plan page **Library Standards** ALA-AASL-2010.1.3 Instructional partner: Candidates model, share, and promote effective principles of teaching and learning as collaborative partners with other educators. Candidates acknowledge the importance of offering professional development to other educators as it relates to library and information use. ALA-AASL-2010.1.4 Integration of twenty-first century skills and learning standards: Candidates advocate for twenty-first century literacy skills to support the learning needs of the school community. Candidates demonstrate how to collaborate with other teachers to plan and implement instruction of the AASL Standards for the 21st-Century Learner and state student curriculum standards. ALA-AASL-2010.3.3 Information technology: Candidates model and facilitate the effective use of current and emerging digital tools to locate, analyze, evaluate, and use information resources to support research, learning, creating, and communicating in a digital society.

 * Tennessee Curriculum Standards**

A –Audience: Students will use an article consisting of population statistics to compute answers to questions, estimate answers to questions, create a bar graph, create a circle graph, and create a line graph. B –Behavior: Students will access a Tennessee Electronic Library database and use it to research answers to questions concerning the population statistics of another country. C –Conditions: Students will create graphs of their population data after research the answers to given questions D –Degree: TLW will be able to create a graph representing population data of a given country with 90% accuracy **Materials, Media, and Resources** Computer lab Tennessee Electronic Library Graph paper Student calculators
 * Instructional Objectives**

__Teacher__ 1. Create a handout using the questions given in the “Steps for Students” section. 2. Access the [|//Tennessee Electronic Library//]. Under the search box, select [|Browse by School Grades]  and then select  [|Middle School Resources] 3. Click on the __ [|Junior Edition (Gale)] [|//__PowerSearch Interface__//] __ 4. Choose a country and calculate the answers to the questions on the handout. 5. Create additional specific grade-appropriate questions about the graphs the students create. 6. Create questions related to predictions. For example, “I predict that the number of people aged 65 and older will be 2 million next year in the United States. Is this likely or unlikely?” or “What are some factors that could occur and cause your prediction to not be accurate?” (natural disaster, war, epidemic)
 * Preparation**

__Teacher__ What’s your favorite restaurant, retail, store, etc.? Do you wish we had one in our town? What types of businesses do we have in our town? Who do they serve? Does anyone know how companies and organizations decide where to locate? They use population statistics to decide where there is a need or an opportunity to make money. We are going to practice working with population statistics of a country and see what kinds of needs this country may have now and in the future.
 * Set Induction**

__Teacher__ 1. Give each student a copy of the prepared hand out. Allow time for them to read and become familiar with it.
 * Instructional Sequence**

__Librarian__ 1. Explain what an electronic database is and how researchers use them to gather data. 2. Direct students to access the [|//Tennessee Electronic Library//]. 3. Under the search box, select [|Browse by School Grades]  and then select  [|Middle School Resources] 4. Click on the __ [|Junior Edition (Gale)] [|//__PowerSearch Interface__//] __ 5. Enter the search terms **nations world** and select Search. 6. Click on the tab for **Books** in the results. 7. This search will yield entries entitled **//“Nations of the world: profiles”//** for various countries; they are arranged alphabetically. Discuss which year should be used for this project. 8. The student should choose an entry that includes the country chosen by the teacher. Show students how to download the PDF version of the book. Discuss how they are seeing the actual print book they could find in a library. 9. Direct students to skim the article.

__Steps for Students__ 1. Based on the data for the entry that includes the chosen country, calculate how many people are born each year in the chosen country. 2. Based on the data for the entry that includes the chosen country, calculate how many people die each year in the chosen country. 3. Which number is greater in the chosen country -- the number of births per year or the number of deaths per year? 4. Estimate how many infants die per year in the chosen country. 5. Answer the following question: In the chosen country, the number of infant deaths per year makes up what percentage of the total number of deaths per year? 6. Calculate how many people are aged 15 or younger in the chosen country and in another country included in the same entry. 7. Create a bar graph showing the number of people aged 15 and younger in the chosen country and in another country listed in the entry. 8. Calculate how many people are aged 65 or older in the chosen country and in another country included in the same entry. 9. Create a pie chart to show the population distribution by age for the chosen country. 10. Answer the following question for the chosen country: What is the ratio of the number of people aged 1-15 to the number of people aged 65 and older? 11. Based on the data in the retrieved entry, calculate how many people live in urban areas in the chosen country and in another country included in the same entry. 12. Estimate the percentage of the population that has Internet access in the chosen country. 13. Answer the following question: If the number of people aged 1-15 increased 10% and the number of people aged 65 and older decreased by 1%, what would happen to the percentage of people aged 16-64? 14. Starting with the year of the data in the article, calculate the projected population to the present and for the next two years following the year for which data is provided. Let the population for a given year equal x. Let the population for the subsequent year equal y. The formula for determining a subsequent year’s population is y = x + 13x/1000. Using this formula and the population given in the article, does this formula yield a population estimate for the year after the year for which data is provided that is higher or lower than a calculation based on the given population plus the number of births minus the number of deaths? 15. Answer the following question: If the number of people aged 65 and older is expected to be ten percent of the population for the year after the year for which data is provided, how many people aged 65 and older will there be? 16. Graph the projected population for the year for which data is given and the next two years following the year for which data is provided.

__Librarian__ 1. Share with students the CIA World Factbook 2. Discuss how this web site is reliable and current (updated weekly). 3. Ask students if this website can be used to find data from previous years. 4. Ask students when else they could use this web site.
