Number grid worksheets turn counting into a pattern puzzle. A number grid arranges the numbers in rows of ten, so that moving down a row adds 10 and moving across adds 1. These free printable number grid worksheets include blank grids to fill in, grids with missing numbers, mystery picture grids and cut-apart puzzles, with an answer key on every PDF and a maker for your own grids.
Quick answer: A number grid is a table of numbers in rows of ten, usually 1 to 100. Moving right adds 1, moving down adds 10, and the pattern makes counting, skip counting and place value easy to see. This page has 15 free number grid worksheets (PDF) with answer keys, plus a maker.

A number grid is a table of numbers arranged in rows of ten, so that each column holds numbers with the same ones digit and each row holds the same tens digit. A 100 number grid runs from 1 to 100. Teachers use it because the layout shows place value without any extra explanation: every square is exactly 10 more than the one above it.
Number grid 1 100: the grid itself
Here is the standard grid. Look for patterns before you print the worksheets: the last column is all multiples of 10, and each column ends in the same digit.

Patterns on a number grid
Moving on the grid is a quick way to add and subtract in tens and ones. These moves give mental math shortcuts that students use for years:
Move on the grid
What changes
Example from 34
Result
One square right
Add 1
34 + 1
35
One square left
Subtract 1
34 − 1
33

Add 10
34 + 10
44
One row up
Subtract 10
34 − 10

Skip counting on a number grid
Highlighting every second, fifth or tenth number reveals the pattern behind each times table. Skip counting is a standard in grade 2 and the base of multiplication in grade 3:
Skip count
Where it lands on the grid
First terms
By 2s
Every second square: all the even numbers
2, 4, 6, 8, 10, 12
By 5s
The 5 and 10 columns
5, 10, 15, 20, 25, 30
By 10s
The last column, straight down
10, 20, 30, 40, 50, 60
By 3s
A diagonal pattern across rows
3, 6, 9, 12, 15, 18
By 9s
A diagonal running down to the left
9, 18, 27, 36, 45, 54
By 11s
A diagonal running down to the right
11, 22, 33, 44, 55, 66
Number grid missing numbers
Missing numbers worksheets ask students to fill in the gaps, using the pattern of the grid as a clue. Here are five rows with the answers beside them:

Odd, even and prime patterns
Shading numbers on a grid shows their patterns at once. Even numbers form stripes, multiples of 10 form the last column, and primes are scattered with no pattern, which surprises many students:

How to use these number grid worksheets
Start with the fill-in-the-grid number grid worksheets so that students have to produce the numbers, not just read them. When counting is fluent, move to the missing numbers worksheets, which test pattern knowledge. The mystery picture grids are a good reward, and the puzzle grids make a nice group activity.
Print the number grid worksheets on card stock and laminate one for a reusable grid with a dry-erase marker. Use the answer keys to check the work together, and ask students to explain how they found each missing number.
