Understanding 100
When we have 99 beads and add 1 more bead, it makes a group of 10 tens, which is called 100 (One Hundred).
Place Value of Three-Digit Numbers
In a three-digit number, digits have different values based on their position: Hundreds, Tens, and Ones.
Reading and Writing Numbers
Numbers from 100 to 999 are read and written using hundred names first, followed by tens and ones (e.g., 345 is Three hundred forty-five).
The Abacus Representation
An abacus tool uses spikes for Hundreds (H), Tens (T), and Ones (O) where beads show the count for each place value.
Expanded Form
Splitting a three-digit number into the sum of its hundreds, tens, and ones is called the expanded form (e.g., 246 = 200 + 40 + 6).
