What’s included
  • PowerPoint lesson (12 slides) with speaker notes on every slide
  • Student worksheet (Word), ready to print or edit
  • Answer sheet (Word) with model answers for every question
B2.2.3 Stacks

By the end of the lesson students can:

  • Explain the LIFO principle and the stack operations push, pop, peek and is_empty
  • Implement a stack in Python using a list
  • Use a stack to solve problems such as undo and bracket checking

Worksheet sections: A. Key words; B. Trace the stack; C. Use a stack; D. Check the brackets; E. Challenge

Every lesson includes
  • Learning goals and a starter question
  • Clear explanations with worked examples (Python where code is needed)
  • A quick check and a “your turnâ€� task linked to the worksheet
  • An exit ticket
