Faye and Brandon work for a charity called The Twinkl Animal Trust. They collect donations of money from people, and use these donations to care for abandoned animals.

They need to round the amounts of money to different values, order the amounts of money collected and compare the amounts donated.

Faye collected a donation of £17.36 from Class 5 at City School. She needs to round this to the nearest £10. Let's look at how she can do this.

Faye collected a donation of £17.36 from Class 5 at City School. She needs to round this to the nearest £10. We are rounding 17.36 to the nearest 10. Firstly, let's identify the tens numbers either side of 17.36.

Faye collected a donation of £17.36 from Class 5 at City School. She needs to round this to the nearest £10. We need to decide whether to round down to 10 or up to 20.

Charity Collection

We look at the digit in the place to the right of the value we are rounding to. Since we are rounding to the nearest 10, we should look at the digit in the ones place.

10 20

In this case, the ones digit is a 7, so we should round up to 20.
