## Inside the Unit...

### Areas Covered

• Lesson 1 Algorithms, decomposition and abstraction
• Lesson 2 Developing algorithms using flowcharts
• Lesson 3 Developing algorithms using pseudocode
• Lesson 4 Searching algorithms
• Lesson 5 Sorting algorithms
• Lesson 6 Assessment

There are 5 worksheets, 5 homework tasks, and an assessment test, each with answers included in this unit.

## Summary

This unit focuses on Section 3.1 Representing algorithms of the AQA specification, and begins by covering decomposition and abstraction. Further lessons in the unit cover algorithms, flowcharts and pseudocode, before looking at specific algorithms for sorting and searching, including the bubble and merge sorts. A final lesson covers the efficiency of algorithms, comparing the processing time and results of different algorithms on the same data sets.

## What's included in the toolkit?

The GCSE units have been written to satisfy the specification for Paper 1 and Paper 2 of the AQA 8520 Computer Science GCSE. Each unit contains:

• PowerPoint slides for each topic
• Detailed lesson plans
• Learning objectives and outcomes
• Worksheets and homework activities with answers
• End-of-unit, exam-style assessment test with answers
• Other material and links to online resources

## What people say...

As I am non-specialist teaching the new specification of AQA GCSE Chemistry for the first time this year, these resources have been invaluable to me. The presentations are thorough and well illustrated. The teacher guide and power point presentation leads you through the topics logically.
