Round numbers to tenths or hundredths

Lesson

To round numbers to tenths or hundredths, it helps to remember:

- why we may need to round numbers
- how we know which digit to change (or leave the same)

This video works through each of those points, and we build up from some simple examples, to examples that have some extra things we need to consider.

Round $95.19$95.19 to the nearest tenth.

Round $11.89572$11.89572 to the nearest tenth.

Round $85.1446$85.1446 to the nearest hundredth.

Know and apply standard form, significant figures, rounding, and decimal place value
