An Introduction to Spreadsheets Using Number Magic What is a spreadsheet? Uses of a spreadsheet. What is Number Magic?
What Is a Spreadsheet? Spreadsheets help with a series of calculations that need to be repeated often. Once they are set up they can be used to explore the effect of changing one number on the others. The data can also be displayed very easily as a graph or chart.
Uses of a Spreadsheet Take rainfall measurements everyday for a week. Set up a spreadsheet to find the total weekly rainfall. A spreadsheet could be set up with the exchange rate of a foreign currency and the pound. The costs of items could be found. A litter survey could be underway for a month. The results could be entered daily into a spreadsheet. These could be displayed and a graph produced of findings.
Number Magic Use for recording, analysing and presenting numerical data. Use the Topic bank to include words and pictures in work. Formula Builder to make automatic calculations simpler. Data can be analysed and rearranged using simple sorting. Can use a wide range of different graphs to present numerical information. Operates on 4 levels of increasing complexity. Detector enables to monitor and record sensory data, such as light levels or temperature.
Moving Around the Spreadsheet Column Letters Cells Active Cell (Cell Address is D6) Row Numbers
