Learner Preparation

A pre-requisite to this lesson is mastery of an Introduction to Spreadsheets lesson.

Lesson Plan

Introduction (LSI Quadrant I): ASK: Have you ever been sitting in class and wondered, “When will I EVER use this in life???” SAY: What if I told you that, today, I would teach you something you’re extremely likely to use in your future, and could even start using right now? SAY: Today we will discuss basic spreadsheet formulas using mathematical operators with which you’re already familiar (such as addition, subtraction, division and multiplication). I will show you how you could use each formula to approach everyday “common” problems.

Outline

Outline (LSI Quadrant II): I. Spreadsheet Terms

A. Excel Formulas – Allow you to perform calculations on data entered into a spreadsheet. The advantage to using an Excel spreadsheet for your formulas rather than a calculator is that, if you change the data in the spreadsheet, Excel will automatically re-calculate the answer for you without you having to re-enter the formula.

B. Data – Information (values, or numbers; labels, or text; and date/time) that is stored in a spreadsheet program.

C. Spreadsheet – A table used to store various types of data.

D. Cells – The basic storage unit for data in a spreadsheet and the intersection point of a column and a row. In

Instructor Notes: Use the Spreadsheet Formulas Vocabulary PowerPoint (pdf) presentation to show terms associated with the lesson. Students should complete the Vocabulary Organizer (pdf). Each slide will include a screenshot of Excel as an example of the

Excel, each rectangular box is referred to as a cell. E. Rows – Rows run horizontally in Excel and are

identified by a number in the row header. F. Columns – Columns run vertically in Excel and are

identified by a letter in the column header. G. Cell Reference – The cell reference identifies the

location of a cell, and consists of the column letter and row number that intersect at the cell’s location.

H. Relative Cell Reference – Default for all Excel cell references. It identifies the location of a cell, and changes when the formula is copied to other cells. In other words, it’s relative to where it is in the spreadsheet.

I. Absolute Cell Reference – In contrast to relative cell references, an absolute cell reference does not change when it is copied and pasted to other cells. In other words, it will absolutely reference the same cell no matter where it is in the spreadsheet.

II. Relevance of Spreadsheets to Everyday Life

A. Purpose of a spreadsheet 1. Keep track of money 2. Keep up with statistics 3. Managing information 4. Analyzing information 5. Presenting information

B. Before electronic spreadsheets… 1. How do you think businesses kept up with

finances, payroll, inventory, etc. before computers?

2. How do you think electronic spreadsheets have transformed businesses today?

C. Some ways that spreadsheets can be used in everyday life: 1. Sports Stats (ex. batting average) 2. Grades 3. Budgets 4. Inventory 5. Buying a Car (comparison shopping)

III. Using Formulas in Excel A. Formulas

concept/term. Feel free to toggle back and forth between PowerPoint and MS Excel to further explain/demonstrate the concepts. Use this website to show your class some “everyday uses” for spreadsheets that are relevant and meaningful to them: www.belmar.k12.nj.us/public/everyday_spreadsheets.

Use the Spreadsheet Formulas PowerPoint (pdf) to present the outline II.-V. Students should complete the Spreadsheet Formulas Organizer. Ask: How do you think businesses kept up with finances, payroll, inventory etc. before computers? How do you think electronic spreadsheets have transformed businesses today? Brainstorm ways that spreadsheets can be used in everyday life and relate them to the items in II. B. 1-5. SEE GUIDED PRACTICE: After presenting the slides in III. A.-B., use the My Stocks Investments

3. Multiplication 4. Division

B. Relative Vs. Absolute

IV. Assignment: Create a spreadsheet with formulas A. Addition B. Subtraction C. Multiplication D. Division E. Relative Cell References

V. Think of your own personal spreadsheet need and use

the formulas from this lesson in the spreadsheet. Fill in your personal spreadsheet topic on your organizer.

Demonstration Excel file to demonstrate the addition, subtraction, multiplication, and division formulas, as well as relative cell references when a formula is copied. Refer to: the Directions for Demonstration (pdf) document for the steps to demonstrate these formulas. Ask for one or two volunteers to re-demonstrate in front of peers. Encourage students watching to peer coach and evaluate the student demonstrator. After outline I.-III. is finished, Explain the Spreadsheet Formulas Assignment (pdf). Students will think of their own personal spreadsheet need and use the formulas in the lesson in their spreadsheet – ex. personal budget, grade computation, sports averages, calories for the day etc. Review the Spreadsheet Formulas Assignment Rubric (pdf) with the students.

Copy and paste Multiple Intelligences Graphic in appropriate place in left column.

Guided Practice (LSI Quadrant III): The teacher will use the My Stocks Investments Demonstration Excel file to demonstrate the addition, subtraction, multiplication, and division formulas, as well as relative cell references when a formula is copied. Volunteers will re-demonstrate in front of peers. Students watching will peer coach and evaluate the student demonstrator.

Independent Practice (LSI Quadrant III): Students will complete the Spreadsheet Formulas Assignment (pdf) independently.

Summary

Review (LSI Quadrants I and IV): Q&A Session Q: For what reasons are spreadsheets used? A: Spreadsheets are an accurate and easy way to keep track of money, statistics, and information,

analyze information, and present it in a way that makes sense to someone else.

Q: What are some “everyday uses” for spreadsheets? A: Answers will vary, but should coincide with the Brainstorm from the lesson. Ex. Sports statistics,

grades, budgets, inventory, buying a car etc. Q: What is an Excel formula? A: An excel formula allows you to perform calculations on data entered into a spreadsheet. Students

might also answer using the actual formula (i.e. addition, subtraction, multiplication, division). If so, re-direct them to the real definition.

Q: What’s the difference between a row and a column? A: A row runs horizontally and is identified by a number, and a column runs vertically and is identified by

a letter. Q: What does the intersection of a row and a column tell us? A: The location of a cell. Ex. Cell A1 is Column A, Row 1. This is called the cell reference. Q: What’s the difference between a relative and an absolute cell reference? A: A relative cell reference identifies the location of a cell and changes when the formula is copied to

other cells. In contrast, an absolute cell reference does not change when it is copied and pasted to other cells.

Evaluation

Informal Assessment (LSI Quadrant III): Teacher will observe student demonstrators and student observers during guided practice to assess student understanding of concepts and techniques. Revision/re-teach will occur as needed before moving to Independent Practice portion of the lesson.

Teacher will circulate through the lab as students work independently to redirect/re-teach as

Basic Spreadsheet Formulas

Demonstration/Guided Practice Notes for Instructor

Using the „My Stocks and Investments‟ example, you will demonstrate

manually typing in formulas and point-and-click formulas for the class.

This might require some background on the nature of investing and

computing gain/loss.

Minimize the PowerPoint, and open the file.

Using Cell F3, type in the formula „=d3*e3‟. Show how excel returns

the value within the cell and references cell d3 and e3.

Delete the formula, and now do the same thing with Point and click.

Type =, point to cell d3, click it – type in the „*‟ symbol and click cell

e3.

Delete the formula again, and have a student demonstrate/replicate

what you just did – or if you‟re in a lab environment, have the class

enter the data and enter the formulas with you.

Now show how this “relative formula” morphs itself when copied down

the column. Ex – the formula becomes =d4*e4.

Do the same thing for Current Value (formula will be =d3*g3),

Gain/Loss (formula will be =h3-f3), and percent gain loss (formula will

be =i3/f3). Again, demonstrate the relative nature of the formulas.

Next, demonstrate the addition/Sum formula in cell d7 by typing in

=d3+d4+d5+d6 to get the total number of shares.
