Rounding numbers up and down

Today we were rounding numbers to the nearest 10.

Here are some rules we made:

If a number ends in 5 you round it up to the nearest 10.

If a number ends in 6, 7, 8 or 9 you round it up to the nearest 10.

If a number ends in 1, 2, 3 or 4 you round it down to the nearest 10.

Abbi – I found this really easy.

Lorna – Our next step is rounding to the nearest 100

Lewis – This was really easy.

Angus – I found this easy and fun.  I had to use my addition and subtraction skills to work out which 10 was the closest.

We are going to test our rules for rounding to 100s and see if they work or if we need to change them.

Check back to see how we get on rounding to 100s.
