OCR GCSE (J277) Computer Science - Algorithms Resource Pack

In-depth coverage of the importance of algorithms in the planning of computer programs. Introduces students to analysing simple problems before exploring progressively more complex problems using flowcharts and pseudo code.

Presented in two parts:

  • Part 1: Seven chapters of theory, interspersed with task prompts. Give to students in its entirety or as separate handouts as and when you need them.
  • Part 2: Worksheets (for completion of the tasks referred to in Part 1), plus solutions

By breaking down algorithms with clear images and relevant examples, it allows students to engage with abstract ideas in a tangible way
