🧮 Putting Numbers in Place Value (Hundreds, Tens, Ones)
This skill introduces the structure of numbers and what every number stands for depending on its place. Thanks to this concept, children understand math better and can work with bigger numbers. Having a firm grasp of place value helps with addition, subtraction, and mental ways of solving math problems. Learning is more enjoyable when we use visual tools and place value models.
🔢 What is Place Value?
Place value tells us how much each digit in a number is worth, depending on where it is (its place).
We read numbers by breaking them into Hundreds, Tens, and Ones.
✏️ Let's Look at the Number 243
243 = 2 Hundreds + 4 Tens + 3 Ones
- 2 is in the Hundreds place → 2 × 100 = 200
- 4 is in the Tens place → 4 × 10 = 40
- 3 is in the Ones place → 3 × 1 = 3
👉 So, 243 = 200 + 40 + 3
This helps us understand how big each part of the number is.
✏️ Another Example: 506
506 = 5 Hundreds + 0 Tens + 6 Ones
Even if the Tens is 0, it still has a place!
👉 506 = 500 + 0 + 6

Expanded Form
Kids often break up numbers into hundreds, tens, and ones to figure out their importance (for example, 326 equals 300 plus 20 plus 6). Expanded form makes it easier for children to notice how each number is counted when making a total. This strengthens a person's ability to work with place value and decompose numbers. It additionally helps students handle bigger numbers by focusing on structure and order.

Which expanded form matches 408?
Comparing Numbers
Kids compare numbers by glancing at their digits to figure out whether one is smaller, larger, or identical to the other. Children learn to use >, <, and = to represent their comparisons. Matching up different numbers improves your critical thinking capabilities and the way you reason. Doing things like looking up prices or checking the scores of products makes applying this skill helpful.
