Class 6 Computer Science
A full year: what the parts of a computer actually do, how it counts in nothing but 0s and 1s, where your files live, how to write and follow an algorithm, and your first look at the tags behind a web page.

- Parts of a computerLesson
Name the main parts of a computer system, say what each one does, and follow the input-process-output cycle.
- Input and output devicesLesson
Decide whether a device is an input or an output device by asking which way the information travels.
- Storage and memoryLesson
Measure information in bits and bytes, work out the bigger units from the smaller ones, and tell memory that forgets from storage that keeps.
How a Computer Counts
Working with Files
Thinking in Steps
- What is an algorithm?Lesson
Follow an algorithm step by step to find what it produces, and explain why changing the order of the steps changes the answer.
- Flowchart symbolsLesson
Name the four flowchart symbols and choose the right one for a step, a question, a start and an input or output.
- Following a flowchartLesson
Trace a flowchart from start to stop, take the right arrow out of a decision, and say what it prints.
- Repeating with loopsLesson
Read a loop, work out how many times it runs, and follow the value it builds up to the end.
- Making decisions in programsLesson
Test whether a condition is true, and work out which branch of an if-otherwise step a program takes.
