About rounding to the nearest 10 and 100
Rounding is the foundation of estimation, and estimation is what stops a child handing in an answer of 4,000 when it should have been 40. It is a habit more than a skill.
The sheets mix rounding to ten and to a hundred on the same page on purpose. A page of identical questions gets answered by rhythm rather than by thinking.
What actually helps
- A number line beats a rule. Ask which ten it is nearer to.
- Deal with the 5 case explicitly — most curricula round it up, but say so out loud.
- Use it for real: estimate the shopping total before the till.
Common questions
Do you round 5 up or down?
Most school curricula round 5 up, so 45 becomes 50. It is a convention rather than a mathematical truth, so it is worth telling a child that explicitly.
Why teach rounding at all when calculators exist?
Because rounding is how you notice a calculator answer is wrong. Estimation is an error-detection skill, not a computation one.
Thank you — that genuinely helps.
