1. Let it snow, let it snow, let it... – Some Reminders – Back up your work! – READ, READ, READ!!! Your Book Your Lab Manual The Course site – WORK, WORK, WORK!!! It is your role to THINK, PLAN, PROCESS, DEVELOP, and DESIGN your projects. – COMMUNICATE!!!

2. Scaffolding What is it? What does it look like in classrooms? G&G p. 69

3. Spreadsheets Moving from Productivity Tool to Thinking Tool

4. Buying a … You have decided to buy a car. You must determine what will be a comfortable monthly payment for you. Design a spreadsheet that will help you outline your personal budget, then decide what car and payment you can afford. 1) What if the interest rate was 2.5%? 5.0%? 9.1%? 2) What if your monthly payment was $100? $250? $400?

5. Recognized as a Common ‘Mathematical’ Tool Manipulating numbers is part of mathematics But...storing and interpreting numerical data and asking questions about the data is essential to other content areas  “What total electoral vote would have resulted if a particular presidential candidate had received 5 percent more votes in a specific block of southern states?”  “How much would a 200-pound man weigh if he were transported to each of the other known planets?”  “Is it colder in November in Fargo, ND or in Juneau, AK?”

6. A spreadsheet is... a tool that allows you to manipulate numbers (and words) and generate chart, graphs and reports. a matrix of intersecting rows and columns. a grid with columns designated by letters and rows designated by numbers on the left side. - G & G p. 100-105

7. Basic SS Terminology Columns (A, B,…) and Rows (1, 2,…) Cell - intersection of column and row Cells may contain -- Text and Values – Letters – Numbers – Formulas - mathematical equations – Functions - built in formulas (average, sum,...)

8. ColumnsCell Rows

9. What can we do with a SS? Traditional purpose:preparing budgets and financial forecasting Store and manipulate data for analysis; compare and contrast statistics Perform calculations Display data (charts and graphs) Ask hypothetical questions -- What if?

10. Basic SS Functions Storing (numerical) information Calculating information Presenting information Critical thinking skills: collecting, organizing, describing, identifying relationships, hypothesizing, interpreting, analyzing data, etc. (NOT limited to Math/older students) Bloom’s Taxonomy - (M p. 18) Application, Analysis, Synthesis, Evaluation

11. Classroom Applications Administrative Uses (for Teachers) – grade book, budget, statistics Instructional Uses (for Students) – teacher-created spreadsheet (provide initial scaffolding) – student-created spreadsheet Instructional Focus – PBL – What if? scenarios

12. Some Spreadsheet Ideas... How much will it cost to keep a pet? How much water and money is wasted by a dripping faucet? Temperature comparisons Compare various characteristics of cities (snowfall, crime rate, population) to assess quality of life Counting, adding, comparing data -- M&M’s, coins, height, pets Science: Plant growth, doubling rate, half-life, etc.

13. Some Spreadsheet Ideas... Survey job opportunities to determine average salaries Determine needs for a class fundraising event by analyzing possible costs and profits Longitudinal analysis (voting, birth and death rates, war statistics) -- any interesting patterns or hypotheses? Compare food prices, nutritional intake, effects of different types of exercise on heart rate

14. Problem: It is your job to take care of a house for one MONTH (30 days). Which payment method would you prefer? Calculate totals for the options below: A) lump sum of $10,000 B) $25.25/hr for 5 hours per day C) $0.01 -- doubles each day D) $155 per day

15. Remember your math symbols… + - ( ) ^ / * > < addition subtraction multiplication division parenthesis exponent greater than less than not equal to

16. Formulas vs. Functions Formulas: Stated numerical relationships between the contents of different cells l =A1+B1+C1+D1+E1 Functions: Mathematical or logical operations that may be performed on the values in a set of specified cells (built in formulas) l =SUM (B1:B9) l =IF B9<B10, B9*E6 Values automatically adjusted l ‘Fill’ command l (Down, right, up, left)

17. How Old Are You? Design a spreadsheet for the following…(Think about layout!) Getting feedback on your age! How old you are in years? …months? …weeks? …days? …hours? …minutes? …seconds?

19. Hunter Taxonomy Framework that helps to define ways to use SS/DB with students. Using - using and manipulating a completed spreadsheet; all data are in the file. Plan a Trip Hunters Taxonomy

20. Hunter Taxonomy: Ways to use SS/DB with Students Building - building a spreadsheet by entering the data into the cells; a template with labels and formulas is created, students need to find and enter data for cells. Software: Excel Counting M&Ms Software: The Graph Club

21. Creating - creating an entire spreadsheet; create layout, organize and enter labels, enter formulas and functions, enter data and manipulate data to solve problems. Buying a Car Software: Excel, Numbers Hunter Taxonomy: Ways to use SS/DB with Students

22. Next... Begin planning for your learning tools project. Focus on the learning objective. What content area standards are being addressed? What questions might be asked? Hunters Taxonomy What tool is appropriate for the job? Library Media - Pick a content area
