Rounding numbers: a worked example (Round 367)
- To the nearest 10: look at the ones digit, 7. It is 5 or more, so round up to 370.
- To the nearest 100: look at the tens digit, 6. It is 5 or more, so round up to 400.
- The digit to the right decides.
How to use it at home and in class
At home
Draw a number line from 360 to 370 and mark 367 to see which ten it is closer to. Ten problems a day works better than a whole sheet at once. Mark them together with the answer key, then ask your child to explain one they got wrong: finding the mistake themselves is where the learning happens.
In class
Use the first row as a warm-up, a full page for independent practice, or five questions as an exit ticket. For a retake or a second group, make a new version with the test maker so every child gets different numbers.
Mistakes to watch for
- Looking at the wrong digit, like the ones digit when rounding to the nearest 100.
- Changing digits to the right into anything other than zeros.
What to practice before and after rounding numbers
- Before: comparing numbers. If this sheet is a struggle, go back a step.
- Learn it first: the rounding numbers lesson and the estimation and rounding chart.
