A comprehensive overview of math concepts and skills for Primary 3 students preparing for the ISEE.
Numbers are everywhere! From counting candies to keeping track of your age, numbers help us make sense of the world. Place value helps us know how much each digit in a number is worth based on its position.
Every number is made up of digits. Each digit has a value depending on its place: ones, tens, hundreds, and so on.
| Hundreds | Tens | Ones |
|---|---|---|
| 4 | 2 | 7 |
In 427, the 4 is in the hundreds place, so it means 400. The 2 is in the tens place, so it means 20. The 7 is in the ones place, so it means 7.
Place value helps you read, write, and compare numbers, which is important for solving math problems and understanding the world around you.
If you have $427 in your piggy bank, knowing place value tells you how many hundreds, tens, and ones you have!
345 is made of 3 hundreds, 4 tens, and 5 ones.
The number 506 means 5 hundreds, 0 tens, and 6 ones.
Place value tells us what each digit in a number stands for.
