A B C D E F G H I J K L M N O P Q R S T U V W X Y Z

Overview

Tools help us do jobs. Look at these tools.

 

A pencil is a tool. It is used to write down information. A pair of scissors is a tool. It can cut paper, string, and paper.

We use tools in math too.

 

A pencil is a math tool. We use it to write numbers and draw shapes. The ruler is a math tool. We use it to measure objects and draw lines.

The hundred chart is also a math tool. This tool can help you do lots of things in math. It helps you count to 100. It helps you skip count. It helps you find patterns. It can help you add and subtract.

Using The Hundred Chart To Count

Let’s use the hundred chart to count to 10.

Put your finger on 1 and say one. Move to 2 and say two. Keep moving your finger to the right and say each number until you reach 10.

You can start any place on the hundred chart and begin counting. Let’s start at 42 and count to 50. Put your finger on 42 and say forty-two. Put your finger on 43 and say forty-three. Put your finger on 44 and say forty-four. Keep moving your finger to the right and say each number until you reach 50.

You can also use the hundred chart to count backwards. Let’s start at 13 and count backwards to 9. Put your finger on 13 and say thirteen. Now move your finger to the left, put it on 12 and say twelve. Put your finger on 11 and say eleven. Since we are at the beginning of the row and we are counting backwards, we need to move up to the next row and continue to count from the end of the row. Put your finger on 10 and say ten. Finally, put your finger on 9 and say nine.

 

Use The Hundred Chart To Skip Count

A hundred chart can help you skip count. Look at the chart. This chart shows you how to skip count by two. Start at 2 and color it in. Count 2 squares and color in 4. Count 2 squares and color in 6.

Using The Hundred Chart To Find Patterns

Look at the hundred chart that we used to show skip counting. We can use it to see patterns. When we skip count by twos every other square is colored in. Now put your finger on 4 and move your finger down. Every number in this column ends in 4. This is another pattern.

Use The Hundred Chart To Add And Subtract

You can also use the hundred chart to add and subtract numbers.
Let’s add

24 + 3.

Put your finger on 24. Count 3 squares forward. Now we are on 27.

24 + 3 = 27.

Let’s subtract

19 – 5.

Put your finger on 19. Count back 5 squares. Now we are on 14.

19 – 5 = 14.

Practice Question 1

Look at the hundreds chart. Let’s count backwards from 21 to 17.

First, put your finger on 21. Since we are at the beginning of the row and we are counting backwards, we need to move up to the next row and continue to count from the end of that row. Put your finger on 20 and say twenty. Put your finger on 19 and say nineteen. Put your finger on 18 and say eighteen. Put your finger on 17 and say seventeen.

TIP:

Practice Question 2

Look at this hundreds chart. What skip counting pattern is shown?

Find the first number that is colored in pink. It is the number 3. Move to the next number. We are going to count until we reach the next number that is colored in pink. To find the pattern we count the squares. We don’t say the number inside the square.

How many squares did we count before we reached the next pink square?

We counted 3 squares.

Let’s do this one more time.

How many squares did we count before we reached the next pink square?

We counted 3 squares. Every three squares are colored in pink. This means that the chart shows that it is skip counting by three.
