__Larger numbers can be rounded in just the same way as rounding hundreds or thousands, always referring to the digit below the one you want to round.__

Eg rounding to a million, look at the hundred thousand digit:

2 **3**45 456 is rounded down to 2 000 000 (two million) to the nearest million because the hundred thousand digit is only 3.

2 **9**87 654 is rounded up to 3 000 000 (three million) to the nearest million because the hundred thousand digit is 9.

Children are often fascinated by large numbers and there are plenty of good sources in geography, such as population figures, areas of countries etc
