### Rounding of numbers to the nearest 10 and 100

Hi Everyone,

I am super excited that I am posting my first blog post. Although I am running my TPT store for a while, but this was something I always wished to start.

Today, I am going to share some of my work on the topic Rounding to the nearest 10 and 100. Typically rounding is introduced in Grade 3. The supporting common core standard is:

Math 3.NBT.A.1: Use place value understanding to round whole numbers to the nearest 10 or 100.

Rounding of a number means replacing it by another number that is approximately of equal value but making it simpler. This is an important skill for students to build on their number sense. For some students, performing rounding of numbers can be quite confusing. My motive was to make something simple, interactive and yet effective to help the little learners understand the concept of rounding.

I am a big fan of Anchor Charts which are created during the instruction of topic. These goes a long way in reinforcing the unit and students can reference it back too!

In my rounding to the nearest 10, 100, and 1000 resource pack, the initial worksheets are focused on Rounding on Number Lines to the nearest 10. This will help students visualize the halfway number and identify the closest number they are rounding it to. Once they understand the concept behind rounding to the nearest ten they can apply it to all other rounding!

### Rounding Sort Game

This is my favorite game on this topic to practice the rounding of numbers to the tens, hundreds, and thousands. This game can be used for the whole group, as a math center, or as a challenge activity for early finishers.

 Rounding and Sorting Game Cards

Game includes 3 versions:

Red Cards: Rounding of 2 digit numbers to the nearest ten.

Blue Cards: Rounding of 3 digit numbers to the nearest hundred.

Yellow Cards: Rounding of 4 digit numbers to the nearest thousand.

This game is a part of the above packet, and is also available here separately.

*Note: The pack also includes rounding to the nearest 1,000.

Hope you will find this useful.

Thanks,
