Year 9 – Lesson 3 – In a while, crocodile

Curriculum KS3 Unit Lesson

This lesson revolves around iteration using while loops, offering learners a chance to retrieve and apply relevant knowledge. In the first activities, learners will practise using list operations in iterative contexts.

Learners will be introduced to the similarities between lists and strings, which will be based on what they already know about operations relating to length, membership, and access to individual characters. The final activity requires them to apply these string operations in an iterative context.

Learning objectives

  • Use iteration (while statements) to control the flow of program execution
  • Perform common operations on lists or individual items
  • Perform common operations on strings or individual characters
