Section 1
📘 Place Value
New Concept
The value of each place is determined by its position.
What’s next
Next, you’ll use diagrams and money manipulatives to build and compare three-digit numbers, putting the power of place value into practice.
In this Grade 4 lesson from Saxon Math Intermediate 4, students learn place value for three-digit numbers by using $100, $10, and $1 bill manipulatives to identify the ones, tens, and hundreds places. Students practice writing and comparing money amounts such as $203 and $230 to understand how a digit's position determines its value. The lesson connects the base-ten number system to real-world money, helping students recognize place value in numbers up to the hundreds place.

Section 2
Place Value
The value of each digit in a number is determined by its position. A number like has a digit in the ones place, the tens place, and the hundreds place.
In the number , the represents hundreds, the represents tens, and the represents ones.
The number can be shown as hundred-dollar bills, ten-dollar bills, and one-dollar bills.
The number is composed of a in the hundreds place, a in the tens place, and a in the ones place.
Think of it like building with money! A one-dollar bill is different from a ten-dollar bill. A digit’s position tells you if you are dealing with ones, tens, or hundreds. It is all about location, location, location!
Section 3
The Power of Zero
A zero in a number acts as a placeholder, indicating that there is no value in that specific place. For example, the zero in dollars represents an absence of tens.
The amount dollars means you have hundred-dollar bills and one-dollar bills, with ten-dollar bills.
The amount dollars means you have hundred-dollar bills and ten-dollar bills, with one-dollar bills.
Therefore, dollars is greater than dollars because three tens are more valuable than three ones.
Zero is a superhero that holds a spot open! In , it shouts, “No tens here!” But in , it declares, “No ones!” This humble hero ensures all other digits stay in their rightful places.
Section 4
Identifying Digit Places
To identify a digit's place value, count its position from the right. The sequence is ones, then tens, then hundreds. The third position from the right is always the hundreds place.
In the number , the digit is in the third position from the right, which is the hundreds place.
In the number , the digit is in the second position from the right, making it the tens place.
In the number , the digit is in the third position from the right, so it is in the hundreds place.
It is like finding your seat in a theater! The first seat on the right is 'ones,' the next is 'tens,' and the third is 'hundreds.' Just count from the right to discover each digit's mighty value.
