Breaking Down the Number

When given a number like 324, it can be helpful to break it down into its individual components:

• Hundreds: 3 hundreds (300)

• Tens: 2 tens (20)

• Ones: 4 ones (4)

Subtracting 10 from 324

Let's start by subtracting 10 from 324:

1. Identify the place values: 324 consists of 3 hundreds, 2 tens, and 4 ones.

2. Subtract 10 (which is 1 ten and 0 ones):Hundreds remain the same: 3 hundreds.
   Tens: 2 tens - 1 ten = 1 ten.
   Ones remain the same: 4 ones.
   

3. The new number is 314 (3 hundreds, 1 ten, and 4 ones).

Subtracting 100 from 324

Now, subtract 100 from 324:

1. Identify the place values: 324 consists of 3 hundreds, 2 tens, and 4 ones.

2. Subtract 100 (which is 1 hundred, 0 tens, and 0 ones):Hundreds: 3 hundreds - 1 hundred = 2 hundreds.
   Tens remain the same: 2 tens.
   Ones remain the same: 4 ones.
   

3. The new number is 224 (2 hundreds, 2 tens, and 4 ones).

Visualizing the Subtraction

Visual aids, like blocks, can help understand the subtraction process. For example, if you have 324 blocks:

• Subtracting 10 means removing one group of 10 blocks, leaving 314 blocks.

• Subtracting 100 means removing one group of 100 blocks, leaving 224 blocks.

By practicing these steps and using visual aids, students can easily master the process of subtracting 1, 10, or 100 from any number.
