Mr Watson’s Introduction to Spreadsheets The ‘Quick’ and ‘Easy’ guide to using Microsoft Excel
By the end of the lesson, I want you to be able to say… “I know what a spreadsheet is, I can enter simple data into a spreadsheet, and I can use simple formulae to perform calculations. With help I can create simple graphs”
Starting at the Beginning What is a Spreadsheet? A spreadsheet is a powerful tool for organising information. What are they for? They are used to carry out lots of calculations quickly and to store large amounts of information for a range of purposes. What can they do? Once you know how to do it – they can do almost any maths that you could need!
So, how do they work then? Rows (Side to Side) [Numbered] Columns (Up and Down) [Letters] Cell (Every one on these boxes is a cell) Every cell has a name to help you find the right one. Its name starts with the column letter and then the row number. So, this cell is called what? F22
Using formulae Login and open Microsoft Excel Entering data in spreadsheets is really easy! You just click on the cell and type it in. Let’s do something more difficult then! Let’s use some formulae (that means sums!) In Numeracy, when we write a number sentence we write the ‘=’ sign just before the answer, in a spreadsheet we write it first, before the sum. So when you want a spreadsheet to work out a sum: PUT THE = FIRST! If you don’t it won’t work.
Using formulae There is one more thing that you need to know About using a spreadsheets to perform calculations. The symbols for the operations are not all the same. So to calculate 3x4 You would enter =3*4 And the spreadsheet would show “12”. (That’s the answer!)
Task one Open a new page in Microsoft Excel. • Enter this data as shown in the right cells. • We are going to make up some Multiplication tables. Click on cell B2. • Enter the number 7 • Highlight the column from B2 to B13 • On the Menu bar. Select: Edit – Fill – Down. The whole column will fill with 7’s. • Click on cell C2. We are going to enter the calculation. • What do we need to enter first?
Task one =a2*b2 This is because these are the cells with the numbers we want to multiply. Note want happens when you enter the formula. Now use the same method that you used to FILL column B with 7’s to repeat the formula in column C. Can you remember how?
Task one If you have done it right, which you will have done! Your spreadsheet should look like this. Task Two: In a new spreadsheet, can you create the 8x table using the techniques we have learned so far.
Task Three PE Kit You receive a letter from your teacher. It tells you what PE you need for the new term. You need: 2 T-shirts, 2 pairs of shorts, 2 pairs of socks, a pair of trainers for outdoors and a pair of plimsolls for indoors Open a new document and enter this information into the correct cells.
Task Three With the information shown above you can calculate the cost of you new PE Kit for yourself. Fill in cells D2, D3, D4, D5 and D6. Now select cell D7 and click on this symbol on the toolbar . Press RETURN and the column total appears Use multiplication to fill column E and F, and use to total up the columns.
Task four Creating Graphs You can use spreadsheets to create graphs of your data. Of course you will need some data to make graphs of! Open a new spreadsheet and set up the columns and rows as shown here. Now you need to find out how many boys and how many girls are in each year group. Find out and enter the data. In column D use a formula to add up the totals. Click on B10 Then click on on the toolbar.
Task four Creating Graphs This tool allows you to add up column totals. Click on B3, hold down the shift key and click on B8. The column total should appear in B10. Use this method to complete the rest of this spreadsheet. Now you are ready to create a graph! It is easy – but watch carefully!!
Task four • Select the data you are going to graph. • Now you are ready to create a graph! Find this icon and click it. • Select the column graph and click NEXT. • Click the ‘Series’ tab. Change each series, Series 1 – Boys, Series 2 – Girls, and Series 3 – Total. • Click NEXT and give your chart a title and label the X and Y axis. • Click NEXT, choose to place chart in new sheet, then click FINISH. • Now you can print your chart. • It’s that simple!!
Congratulations! Did you manage it? Of course you did! Can you say it then? “I know what a spreadsheet is, I can enter simple data into a spreadsheet, and I can use simple formulae to perform calculations. With help I can create simple graphs.”
