We used a number line to help us develop our number sense as we round. This method might be new to you. Check out this brief video where it is clearly explained.
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.)
Tomorrow we will practice rounding to the nearest 100. We will also use a number line to help us develop our number sense as we round to one hundred. This brief video will explain it clearly.
The trickiest part for some children is figuring out what the choices are. For example, if I am rounding 361 to the nearest hundred, I need to find the closest multiples of 100. Children need to know that 361 is between 300 and 400. Once they have determined this, they can see that 361 rounds to 400 because 360 is closer to 400 than 300.
Happy rounding! :o)
