How to use the 100 chart
You can also hide the numbers and tap to find them. It works on phones, tablets and computers, with no sign-up.
- Tap any number to color it. Pick Blue, Gold or Green first if you want to sort numbers into groups. Tap a colored number again to clear it.
- Press 1–120 to add two more rows. Press 1–100 to go back.
- Press 2s, 5s or 10s to light up that pattern. Count along out loud: 5, 10, 15, 20.
- Press Hide numbers to blank the chart. Tap a square to see which number is there, then tap it again to cover it.
- Press Clear to start over.
What is a 100 chart?
A 100 chart is a grid of the numbers 1 to 100 in ten rows of ten. Many teachers call it a hundred chart or a hundreds chart, and in the UK it is usually called a hundred square or a 100 square. A 120 chart carries on to 120, because first graders count that far.
Every row has ten numbers, so numbers in the same column share a last digit, and the number below any square is 10 more. Children spot these patterns for themselves when they color the numbers they say while skip counting.
Ideas to try at home
- Color every 10 and ask what you notice. All the colored squares sit in one column, and every number ends in 0.
- Pick a number and ask, "What is 10 more?" Slide your finger one square down to check.
- Count by 5s together while your child colors. Then do 2s in a second color and look at where the colors overlap.
- Hide the numbers, point to a square and ask your child to guess it. Tap it to see.
- Cover a few squares at a time and ask which numbers are missing from a row.
- Start at any number and count on to 120, tapping each square as you say it.
What it helps with
- Counting: saying the numbers in order to 100, and then to 120, from any starting point.
- Skip counting: counting by 2s, 5s and 10s, and spotting the pattern in the last digit.
- Place value: seeing that one square down is 10 more and one square up is 10 less.
Common Core standards that fit this tool, in the standards' own words:

Questions about the 100 chart
What is a 100 chart used for?
A 100 chart is used to practice counting to 100, skip counting and number patterns. Children color or point to numbers and find that one square down is 10 more. Counting by 10s fills one column, and counting by 5s or 2s makes stripes of columns.
What is the difference between a 100 chart and a 120 chart?
A 120 chart is a 100 chart with two more rows, so it runs from 1 to 120. First graders learn to count to 120, so the longer chart fits them. This tool switches between the two with one button.
What ages is the 100 chart for?
The 100 chart suits ages 5 to 8. Kindergartners count to 100 and by tens on it, first graders count to 120 and find 10 more or 10 less, and second graders use it to see patterns in counting by 5s and 10s.
Can I print this 100 chart?
Not from this page. It is made for a screen, and nothing you color is saved. For a paper chart, write the numbers 1 to 100 in ten rows of ten with your child. Writing them out is good counting practice too.
