## What is place value in Grade 3?

Place value is the value of each digit in a number. For example, the 5 in 350 represents 5 tens, or 50; however, the 5 in 5,006 represents 5 thousands, or 5,000. It is important that children understand that whilst a digit can be the same, its value depends on where it is in the number.

### How do you round off numbers example?

Here’s the general rule for rounding:

- If the number you are rounding is followed by 5, 6, 7, 8, or 9, round the number up. Example: 38 rounded to the nearest ten is 40.
- If the number you are rounding is followed by 0, 1, 2, 3, or 4, round the number down. Example: 33 rounded to the nearest ten is 30.

#### How do I start teaching rounding?

The best way to start is by modeling rounding using two-digit numbers and showing children how to round to the nearest ten. Working with your child, ask him or her to think of a number being rounded, and ask what comes before and after that number, and fill in only those two numbers.

**Why do kids struggle with rounding?**

Students who struggle to round numbers most often don’t have a misconception about how to round, they lack an internal number line and the number sense that allows them to be able to round. In other words, it’s not a rounding issue, it’s a number sense issue.

**How can I help my students with rounding?**

## What is a rounding number?

Rounding numbers means adjusting the digits (up or down) to make rough calculations easier. The result will be an estimated answer rather than a precise one.

### What is the difference between value and place value?

What is the Difference Between Place Value and Face Value? Place value is defined as the position that a digit occupies in a number, whereas, face value is the actual value of a digit in a number. For example, in 4538, the place value of 5 is 500 and the face value of 5 is 5 itself.

#### What are the rules of rounding off?

Rule 1: Determine what your rounding digit is and look at the digit to the right of it (highlighted digit). If the highlighted digit is 1, 2, 3, 4 simply drop all digits to the right of rounding digit. Example: 3.423 may be rounded off to 3.42 when rounded off to the nearest hundredths place.

**How do you explain rounding?**

Rounding means making a number simpler but keeping its value close to what it was. The result is less accurate, but easier to use. Example: 73 rounded to the nearest ten is 70, because 73 is closer to 70 than to 80. But 76 goes up to 80.
