**These are real life models…**

main using a spreadsheet modelling using a spreadsheet using a spreadsheet to build a model refining and developing a model ways of presenting data These are real life models… What are these models doing? What other examples of models have you used? starter main plenary homework

**A model is a representation. **

What if the plane landed too quickly? A model is a representation. A model imitates the conditions of a real event. A model allows us to ask What if? And test it! starter main plenary homework

**We are learning to solve problems using a spreadsheet model**

main using a spreadsheet modelling using a spreadsheet using a spreadsheet to build a model refining and developing a model ways of presenting data We are learning to solve problems using a spreadsheet model What I am looking for is students who can interrogate (question) a model to find answers This is because using a model can help you to make decisions starter main plenary homework

main using a spreadsheet modelling using a spreadsheet using a spreadsheet to build a model refining and developing a model ways of presenting data A spreadsheet is a computer programme which allows you to create a number of models Spreadsheets can make it easy to display information. They do this by organising data into columns and rows. Look at the zoo model as a spreadsheet Spreadsheets use formulas to make calculations People use spreadsheet programs to ask What if…? Questions. Look at this model Spreadsheets are extremely useful in everyday life and can produce graphs or charts to help visualise your results. Look at this financial spreadsheet starter main plenary homework

using a spreadsheet modelling using a spreadsheet using a spreadsheet to build a model refining and developing a model ways of presenting data So how did you do? LEVEL 3 LEVEL 4 LEVEL 5 I have entered numbers and text in cells on a spreadsheet model I have used formatting to improve the way they look I used a spreadsheet model to answer some questions I made predications and changed the values of variables in a spreadsheet model to check them I added new variables to a spreadsheet model to make it more realistic I can identify the rules in a model I can identify the rules in a model and explain what they do starter main plenary homework

**The advantages of modelling**

plenary using a spreadsheet modelling using a spreadsheet using a spreadsheet to build a model refining and developing a model ways of presenting data Much cheaper than using the real thing Quick results. Simulation can be speeded up Can simulate dangerous situations The advantages of modelling Allows for data to be changed to see the consequences starter main plenary homework
