Task goals
- Foundation: Round whole numbers and decimals to a given number of decimal places or significant figures, and convert simple large/small numbers between ordinary and standard form.
- Proficient: Perform multiplication and division of numbers given in standard form, and use rounding to estimate the answer to a multi-step calculation before checking it.
- Excellence: Solve real-world problems (e.g. astronomical distances, micro-measurements) requiring standard form arithmetic combined with justified estimation of reasonable error bounds.
