Let’s get the idea.

Here’s how it works

Find the two multiples either side, then choose the closer one.

What we’re exploring

finding the nearest ten and the nearest hundred
which digit decides the round
why a 5 always rounds up

At exactly halfway, round up to the higher multiple.

LET’S WORK ONE OUT TOGETHER

A little example

Round 347 to the nearest 10 and nearest 100.

1
347 is between 340 and 350; it is nearer 350.
2
It is between 300 and 400; it is nearer 300.
3
So the answers are 350 and 300.

Make a little room for your workings.
