In this activity, we will be learning how to round a number to the nearest ten.

Remember that when numbers end in 1, 2, 3 or 4, round down to the nearest ten! When numbers end in 5, 6, 7, 8 or 9, round up to the nearest ten!

Example 1

Round this number to the nearest ten.

741

Answer

741 is between 740 and 750.

Look at the 1 in the ones place. It's less than 5, so round down to 740. 

Example 2

Round this number to the nearest ten.

819

Answer

819 is between 810 and 820.

There is a 9 in the ones place, so we round up to 820.

Does that make sense?
