Bespoke, fully editable lesson for Cambridge International AS & A Level Computer Science (9618): P3.08 Range, precision and rounding errors. Slides, worksheet and full answers.
Written for Paper 3 Advanced Theory, section 13 Data representation (syllabus 13.3.1, 13.3.4, 13.3.5). Everything is editable, so you can adapt it to your class.
What’s included- PowerPoint lesson (14 slides) with teacher notes on every slide
- Student worksheet (Word), ready to print or edit
- Answer sheet (Word) with mark-scheme style answers for every question
By the end of the lesson students can:
- Find the range of a floating-point format and explain how the bit split affects range and precision
- Explain how overflow and underflow happen
- Explain why binary floating point is often only an approximation, and how rounding errors arise and grow
Worksheet sections: A. Key words; B. Find the limits; C. Overflow, underflow or rounding?; D. Exam-style questions; E. Challenge
Every lesson includes- Learning goals and a starter question
- Clear explanations, diagrams and worked examples (Cambridge pseudocode, as in the 2027–2029 pseudocode guide, with Python alongside)
- A quick check and a “your turn” task linked to the worksheet
- Exam-style questions with marks, and an exit ticket
- PowerPoint (.pptx) and Word (.docx), fully editable
