What is a Spreadsheet?
A spreadsheet is an example of a General Purpose Package that is used to help you process, store and calculate numbers.
A B C D E F1 The 6 Times Table23 6 x 1 = 64 6 x 2 = 125 6 x 3 = 186 6 x 4 = 24
Columns/Rows
Columns Boxes that go vertically,
for example, column A
Rows Boxes that go
horizontally, for example, Row 1
Columns/Rows/Cell Reference

Simple Formula
Simple Formula
Addition =A1+A2+A3
Subtraction =A1-A2
Multiplication =A1*A2
Division =A1/A2
Aims of the Lesson 2
Today’s Lesson1. =sum formula
2. Other complex formula
3. Replication
1. Continue with Green Folder
SUM Function
The =sum function is used to add up a list of numbers
=A1 + A2 + A3 +A4 + A5 + A6 + A7 + A8 You would use the formula =sum(A1:A8)
Complex Formula Complex Formula
Adding a list of numbers = sum(A1:A10)
Calculating Averages = average(A1:A10)
Finding the largest = max(A1:A10)
Finding the smallest = min(A1:A10)
Making Decisions =if(A1>65,”OAP”,”young thing”)
Replication Replication is where you copy a formula across
Columns or down Rows Go to the bottom right hand corner and drag
Relative Replication = where the cell reference changes depending on what row you are in
Aims of the Lesson 3
Today’s Lesson1. Note taking
1. Formatting cells
2. Inserting Columns/Rows
3. Cell Protection
2. Continue with Green Folder
Formatting Cells To format a cell, you need to highlight the
appropriate cells then click on the Format Menu
Format to Currency, 2 Decimal Places, Percentage You can also Format the alignment, font colour, style
and cell back colour
Insert Row/Column
Sometimes you need to add an extra row or column if you have forgotten to add information
Adding a Column Right click on the Column after and click on insert
Adding a Row Right click on the Row below and click on insert
Lesson Starter
1. Other than sum, List 3 spreadsheet functions
2. What is the difference between a column and a row?
3. What is the name of the little box where you enter formula?
4. What is formula replication?
Aims of the Lesson 4
Today’s Lesson1. Note taking
1. Cell Protection
2. Absolute Referencing
3. IF Formula
2. Continue with Green Folder
Cell Protection
Cell Protection is where you lock a cell so that the contents can’t be changed
1. Unlock Sheet
2. Highlight cells and lock
3. Protect sheet
Absolute Referencing Absolute Referencing is where you copy a formula
down and the cell referencing always stays the same

Lesson Starter
1. The values in column D have to be formatted to look like those in columns B and C. Describe how this can be done.
2. Complete the following E4 = E10 =
3. Ben wants to stop people from changing his formulae. Explain what feature he must use to stop this happening.
4. What is meant by the term relative replication?

Formula using IF (Credit)
You can use an IF statement in a Spreadsheet to make decisions
For example: =IF(B2>50, “PASS”, “FAIL”)
