Rounding and Significant Figures-Physics

Physics: Mathematical Skills
Rounding, Significant Figures and Decimal Places
For IGCSE, GCSE, A-Level, IAL and IB Physics
Notes, Worksheet, Examples

Analytically this resource includes

• Notes with examples (2 pages), detailed explanation of answers in seperate file.
• Practice Questions (1 page), a total of 92 questions for practice. Answer sheet as a seperate file.

I use this as a starting point for all my high school physics classes. IGCSE, IAL and IB physics.

The notes and examples sheet with answers can be given directly to students. Alternatively you can give them the notes only and walk them trough the examples.

I usually use the practice questions worksheet as homework.
