2. 1. Know the different types of flow block 2. Understand how problems can be broken down into smaller problems

3.  Structured programming is IMPORTANT because it usually makes programs more reliable, easier to read, understand and maintain.  Complex problems are easier to solve as they are broken down into smaller, more practicable steps. How can we add structure to programs?

4.  There are only four fundamental building blocks in programing 1. Sequencing – the order in which statements are executed 2. Selection – the use of logic to select the statement to be executed 3. Iteration – the use of repetition (being lazy!!) 4. Variables – somewhere to store information at run time, very very useful

5. Temperature Conversion Input temperature in Fahrenheit Calculate Temperature Conversion Output Temperature in Centigrade Statements are executed in the order they are written in the program. Here there a 3 steps and they occur in this order:

6.  Flow charts easily show how the flow of the sequences happen  There are lots of different shapes that make a flow diagram, we are only likely to use 5 Flow Arrow Input Block

7. Turn A/C off False Turn on A/C True Temp > 25 End Start Temp

8. So how do you do an if statement? Is it holidays? YAY!!! Holidays Booooo  Booooo  No/FalseYes/True

9.  We are going to have to model a loop as well.  How do you think that we do loops? Turn A/C off False Turn on A/C True Temp > 25 Start Temp

10.  In groups of 2  You are going to come up with a flow diagram to show how to make a cup of tea  We are then going to run your programs in the next lesson. Remember - think about all of the tasks to make the tea
