In this activity, we will compare two large numbers and use the** < (less than) or > (greater than)** symbols.

Numbers will be no larger than 10 million (10,000,000).

We will group digits in threes, placing **commas **between each group.

4,578,025 is the number 4 million, 578 thousand, and 25.

When comparing two numbers, think of placing each digit into the usual columns.

Then start comparing the digits in each column **from the left**.

If the digits are the same in the column being compared, move one column to the right and compare those digits.

**Example 1**

Compare:

**4,275,302 ** _{ } **5,110,243**

**Answer**

When placed in columns, we can compare the millions column.

The first number has only **4** million.

The second number has** 5 **million.

**4,275,302 _{} 5,110,243**

**Example 2**

Compare:

**4,275,302** _{ } **4,210,243**

**Answer**

When placed in columns, we can compare the millions column.

They are both **4** million.

So we go to the next column - the hundred thousands column.

They are both **2** hundred thousand.

So we go to the next column – the ten thousands column.

The first number has **7 **in this column.

The second number has **1** in this column.

**4,275,302 _{} 4,210,243**

**Example 3**

Compare:

**275,302 ** _{ } **2,710,243**

**Answer**

When placed in columns, the number on the right has the digit 2 in the millions column.

The number on the left doesn't have a digit in the millions column. Call it zero.

0 < 2

**275,302 _{ } 2,710,243**

Right, let's get started!
