Unit+6+Task+2

**Today you will learn **

 * how we can use diagrams (flowcharts) to show a set of instructions.
 * how we can make a task easier by breaking it down into smaller ones.
 * why computers need very precise instructions to make them work.
 * how decisions in instructions affect how they are carried out.

** I am looking for you to: **

 * write concise instructions to carry out a simple task
 * understand what the different flowchart symbols mean 

Task Two instructions :
1 Recap on last lesson and look at a flowchart. **View [|7.6 Teacher resource 3.ppt]**. 2 [|pupil_resource_2.1.ppt] shows event table for the lights at a narrow bridge. Use flow diagram symbols to show each step of the sequence. Some steps have been done for you. Use the Traffic Light Sequence and Bridge Light Sequence to remind you of the order in which lights change. Save the following files: [|pupil_resource_2.1-completed.ppt] [|1 traffic light.ppt] [|2 traffic light.ppt] 3 Watch your teacher demonstrate how to start Flowol and create control programs. 4 Copy how the flowchart you have had time to draw into Flowol to control Bridgligh. 5 Make however much of the flowchart you have had time to enter loop back to the first step. View [|teacher_help_7.6.4.ppt]. 6 Watch a demonstration of how to save Flowol programs. **7 ** **Extension:** Make another program in Flowol to allow more traffic to pass one way than the other.
