Spreadsheets

Moving from Productivity Tool to Thinking Tool

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?

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?”

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

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, ...)

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?

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)

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

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.

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

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

Formulas vs. Functions

Formulas: Stated numerical relationships between the contents of different cells

=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)

=SUM (B1:B9)

=IF B9<B10, B9*E6

Values automatically adjusted

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?

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.
