Rounding

This morning we began learning how to round numbers to the nearest ten. The children began to understand that sometimes you need to count with precise accuracy, but other times you can make an estimate. In situations that require only an estimate we round numbers. We looked at a number line so we could visibly see which multiples of 10 (the numbers you count when counting by 10) other numbers are closest too. I directly taught the children that numbers with 5 in the ones place always round up.

You can practice rounding to the nearest 10 at home! Ask your child to round 67 to the nearest 10. (67 rounds up to 70.) Or try 21. (21 rounds down to 20.)

We'll be rounding to the nearest 100 next week.
