What is a Hundreds Chart?

How to Use a Hundreds Chart

A hundreds chart is a tool to see patterns, count, and even add or subtract. A one hundreds chart has the numbers one to one hundred organized into columns and rows. Looking at the squares, you see they count forward by one (...) in rows of ten. When we read a hundreds chart we read it the same way that we read a book, from left to right. Like reading, when we get to the last number on the right we go down to the next row and start from the left again.

You might notice hundreds chart patterns if you look at the columns. You can see that all of the numbers in the ones place of this column have the number two… and that the other columns and rows follow similar patterns.

What happens when you find a hundreds chart with missing numbers? When there is a missing number on a hundreds chart, you can use counting on a hundreds chart and patterns to help fill in the hundreds chart. You can use what you know about place value to help figure out where the missing number will go.

Interactive Hundreds Chart - Practice

Let’s practice finding the missing number using the example below!

Skylar and Henry have the number thirty-four and need to figure out where it goes on the chart! Thirty-four has a three in the tens place, so we can find the other numbers that start with three. Then we can count starting from the first number with a three in the tens place to find where thirty-four goes.

Transcript The Hundreds Chart

: "Let's use this handy map to help us go exploring!" : "Huh, what's that on the back of the map?" : "What are all of these numbers for, and why are some of them missing?" : "Maybe if we figure it out it will help us find treasure!" : "Treeeaaaaaasure!" Skylar and Henry want to find a treasure, but first, they need to learn more about the hundreds chart. What is a hundreds chart? A hundreds chart is a tool to see patterns, count, and even add or subtract. It has the numbers one to one hundred organized into columns and rows. Looking at the squares, you see they count forward by one (...) in rows of ten. You might be able to see a pattern in the ones place of each number. For example, let’s look at the column that starts with the number two. If you look at the ones place in every number of this column, what do you see? Every square vertically has the number two in its ones place. You might notice that other numbers follow this pattern as well... like here, where every square horozontally has the number one in it's tens place. When we read a hundreds chart we read it the same way that we read a book, from left to right. Like reading, when we get to the last number on the right we go down to the next row and start from the left again. It looks like Henry and Skylar found something! : "Henry, look, a box!" : "is it a clue? ....I think thats what's missing!" Let's help Henry and Skylar figure out where this number goes on the hundreds chart to get closer to the treasure! When there is a missing number on a hundreds chart, you can use counting and patterns to help figure out where it goes. Henry and Skylar's number is sixteen. Where should sixteen go on the chart? (...) Sixteen has a one in the tens place so it will go with the other teen numbers that follow this pattern. Let's count the teen numbers to find out where it goes! Eleven (...) twelve (...) thirteen (...) fourteen (...) fifteen (...) sixteen (...) We found it! Sixteen goes after fifteen. : " A wrench! We can use that to tighten the wheels and get to the treasure!" While Henry was tightening the wheels, Skylar noticed another number box! Let's use what we know about the hundreds chart to help them figure out where this number goes. Their next number is forty-four. Since forty-four begins with four, we can start with this row, and count up until we find it's place. Count with me! Forty (...) forty-one (...) forty-two (...) forty-three (...) forty-four! So, forty-four goes after forty-three! : "We got oil! Maybe if we put this on the wheels it will make the train faster and get to the treasure." Before we see what the treasure is, let's review. Today we learned about the hundreds chart. It's a tool with numbers to help count, see patterns, and even add or subtract. We saw how it is organized with columns and rows... and explored how to find missing numbers. Now, let's go see that treasure! : "I wonder what the treasure will be!" : "We're here, we're here! We made it to the treasure!" : "Look Skylar, a house! Our treasure is a house!" : "Wait a second Henry... , that's OUR house."
