Hundreds Chart Worksheets

Make your own hundreds chart: any start number, skip counting, missing numbers, puzzles and mystery pictures.

Quick answer: A 120 chart is a hundreds chart that continues to 120, with 12 rows of 10 numbers. First graders use it to count to 120 from any number (standard 1.NBT.A.1). This page has free printable 120 chart PDFs with missing numbers and a blank chart, each with an answer key. Updated October 2026.

Why use a hundreds chart?

A hundreds chart puts the numbers 1 to 100 in ten rows of ten. Moving right adds one, moving down adds ten. Children who fill in a chart start to notice these patterns on their own: every number in a column ends with the same digit, and each row starts one ten higher.

What is on this page

• Missing numbers: two charts with gaps to fill.
• Blank chart: only the first row and first column are given.
• 21 to 120 chart: grade 1 children count to 120 (1.NBT.A.1).
• Counting to 120 sequences: fill the gaps forwards and backwards.

Hundreds chart worksheets: what is in the set

There are 6 hundreds chart worksheets on this page, and every one has an answer key except for any cut-out games. The first three sets are charts from 1 to 100 with different numbers of gaps, and the last three extend the count to 120 and go forwards and backwards.

Hundreds chart patterns every child should see

A hundreds chart is more than a list of numbers. It is a picture of the number system, and children who fill in a hundreds chart start to notice patterns without being told. The first pattern is the rows. Each row starts one ten higher than the one before it, and the sum of each row goes up by 100:

The total of all ten rows is 5,050. According to a well-known story, the young Carl Friedrich Gauss found this sum in a few seconds by noticing that 1 + 100, 2 + 99 and so on, all make 101, and there are 50 pairs. That makes 50 × 101 = 5,050.

Hundreds chart columns: the ones digit stays the same

Going down a column adds 10 each time, so the ones digit never changes. The table shows four columns with their sums. Children who see this pattern learn that adding 10 changes only the tens digit, which they use for mental addition:

Hundreds chart worksheets: how to move on the chart

Hundreds chart worksheets teach children to add and subtract by moving. Right is +1, left is −1, down is +10 and up is −10. Moving down and to the right is +11, and moving down and to the left is +9. The table shows seven moves from the same starting square:

This is the same as the number line, but in two dimensions, so children also use it for problems such as 34 + 20. The hundreds chart tool makes charts that start at any number, so a teacher can start a chart at 0 or at 101.

Missing numbers hundreds chart: how hard is each worksheet?

A missing numbers hundreds chart gets harder as more numbers are missing. The table shows how many numbers children must fill in on each worksheet, which helps to choose the right one:

On the blank chart only the first row and the first column are given, which is 19 numbers, and the child fills in the other 81. A child who can do this has understood the whole structure of the chart.

Blank hundreds chart: some facts to find

Once a chart is filled in, children can look for patterns. This table gives five facts about the numbers 1 to 100, and the numbers that match. The prime numbers can be found with the sieve of Eratosthenes, in which children cross out the multiples of 2, 3, 5 and 7 and the numbers left are prime:

Counting to 120 worksheets: the 120 chart

The Common Core asks grade 1 children to count to 120, starting at any number (1.NBT.A.1). The counting to 120 worksheets and the 120 chart worksheets add two rows to the hundreds chart. The pattern does not change, but children now meet three-digit numbers, so the last rows are:

Notice that 100 follows 99 at the end of row 10, and 101 starts row 11. The Common Core standards for grade 1 number and operations in base ten describe this standard.

Hundreds chart worksheets can be used for story problems about moving along the chart. Ask children to find the starting number on the chart and to move to the answer:

Games and activities for hundreds chart worksheets

Children learn hundreds chart worksheets best when they play with it. These games use things that are found at home or in a classroom:

• Number hunt: call out a number and let the child point to it on the chart as fast as possible
• Mystery number: cover a number with a counter and ask the child to find it from its neighbors
• Chart race: roll a die and move that number of squares, the first to reach 100 wins
• Color the pattern: color all the numbers that end in 5 or 0 and see the columns
• Jigsaw chart: cut a filled chart into pieces and put them back in order
• Roll and move: roll one die for the rows and one for the squares

Extra support and extra challenge with the hundreds chart

For children who need more support: start with a chart that has only a few gaps, and let children use their finger to move one square at a time. Count aloud in tens down the column. Do not use the blank chart until the child can fill in the chart with 60 gaps.

For children who need more challenge: ask the child to find a number that is 25 more, to color all the multiples of 3 and to find the sum of any row. The chart with the numbers 21 to 120 asks for the next ten and the next hundred.

How to tell that a child is ready to move on from the hundreds chart

1. The child fills in a chart with 60 gaps without counting from 1.
2. The child finds the number ten more or ten less than any number, using the chart.
3. The child counts to 120 starting at any number.
4. The child can explain why every number in a column ends in the same digit.

When all four are true, move on to skip counting, where the chart is used to find patterns of the multiples.

A five-day plan for the hundreds chart

Most children need about a week of short sessions for the hundreds chart. This plan follows the order of the worksheets on this page:

When the plan is complete, go to skip counting. The whole sequence is on the counting worksheets page, and the Common Core standards for grade 1 number and operations in base ten list the standards.
