Bio-numbers
What do nature's numbers look like? Are they big or small? Can we calculate them precisely, or do we have to work through estimation and approximation? These problems provide a range of contexts to practise these vital skills.
Big and Small Numbers in the Living World
Age
11 to 16
Challenge Level
Work with numbers big and small to estimate and calculate various quantities in biological contexts.
