How to use the Hundreds Chart Generator
Pick a chart such as 1–100 or 1–120, or set your own start number, step and number of rows.
Choose which numbers show: the full chart, a blank grid, random missing numbers or only the first column.
Highlight a pattern such as multiples of 5 or prime numbers, or click squares in the preview to color them.
Edit the title and instructions, and turn the name and date line or the answer key on or off.
Download the PDF (or PNG) and print it, or press Print to send it straight to your printer.
Patterns to look for on a hundreds chart
A 1–100 chart has ten columns, so every number sits directly under the number that is 10 less. That single rule creates most of the patterns children discover. Highlight a pattern in the tool, print it and ask students to describe what they see before you explain it.
Highlight
Shape on a 1–100 chart
Why it happens
Multiples of 10
The last column
Each row ends on the next ten
Multiples of 5
Two full columns (5s and 10s)
5 divides 10, so the pattern repeats every row
Multiples of 2
Five columns (every other column)
Even numbers end in 0, 2, 4, 6 or 8
Multiples of 9
A diagonal running down to the left
+9 is one row down (+10) and one square left (−1)
Multiples of 11
The main diagonal from 11 to 99
+11 is one row down and one square right
Multiples of 3
Diagonal stripes going down to the left
+3 three times is +9, the same diagonal shift
Prime numbers
No regular shape; 25 primes below 100
After 2 and 5, primes can only end in 1, 3, 7 or 9
Square numbers
10 squares: 1, 4, 9, 16, 25, 36, 49, 64, 81, 100
The gaps grow by 2 each time (3, 5, 7, 9…)
Classroom activities with printable charts
Missing numbers: start with 10–20% hidden for kindergarten and work up to a blank grid. The answer key page makes self-checking easy.
Plus 10, minus 10: give a filled chart and ask what is one square below or above a number. Students soon notice the tens digit changes and the ones digit stays the same.
Skip counting: use the Count by 2s, 5s or 10s presets for a chart that shows only the sequence, or color the multiples on a normal chart.
Puzzle pieces: print a full chart, cut it into irregular chunks and let students reassemble it by reasoning about the numbers next to each other.
Crossing 100: the 1–120 chart and the 101–200 preset help students see that the pattern continues past 100 exactly as before.
Two charts per page halves the paper you use and is handy for homework strips or math journals; a single chart per page is best for wall displays and younger children with bigger handwriting.
Frequently asked questions
What is a hundreds chart?
A hundreds chart is a 10 by 10 grid that shows the numbers 1 to 100 in order, ten per row. Because every row adds 10, children can see place value at a glance: moving one square right adds 1, moving one square down adds 10. Teachers use it for counting, skip counting, addition and subtraction and spotting number patterns.
What is the difference between a 100 chart and a 120 chart?
A 120 chart adds two more rows (101 to 120). Many US first-grade standards ask students to count, read and write numbers to 120, so the extra rows let them practice crossing 100. Choose the 1–120 preset to make one.
Should the chart start at 0 or 1?
Both are common. A 1–100 chart ends each row on a multiple of ten (10, 20, 30), which matches counting objects. A 0–99 chart puts every number with the same tens digit in one row, which some teachers prefer for place value. Pick whichever matches your curriculum.
How do I make a missing numbers worksheet?
Set Numbers shown to Missing numbers (random), choose what percentage to hide and press Shuffle missing numbers until you like the layout. Leave Add an answer key page checked and the PDF will include a second page with every number filled in, with the answers shown in green.
Which patterns can I highlight?
Multiples of any number from 2 to 12, prime numbers, square numbers (1, 4, 9, 16 and so on) and odd numbers, each in its own color. Multiples of 10 form a column, multiples of 9 form a diagonal and multiples of 11 run corner to corner, which makes good discussion starters.
Will the chart print at the right size?
Yes. The PDF is drawn at the exact paper size you choose (US Letter 8.5 × 11 in or A4) with 14 mm margins, so it fits without scaling. If your printer adds its own margins, choose Fit to page or Actual size in the print dialog; both work for this chart.
Is the hundreds chart generator free?
Yes, it is completely free with no sign-up or watermark. Everything is created in your browser and nothing is uploaded. You can print as many charts as you like for home or classroom use.
