All 22 puzzle pieces

Starter pieces (3 or 4 squares) 7

Column of three Three squares stacked, so each number is 10 more than the one above it. Example on a 1 to 100 chart: 17, 27 and 37.
Row of three Three squares side by side, so each number is 1 more than the one on its left. Example on a 1 to 100 chart: 23, 24 and 25.
Short L Count down the column by tens, then take one step right. Example on a 1 to 100 chart: 61, 71, 81 and 82.
Short T A row of three with one square hanging under the middle, 10 more than the number above it. Example on a 1 to 100 chart: 12, 13, 14 and 23.
Small corner One step down, then one step right: add 10, then add 1. Example on a 1 to 100 chart: 52, 62 and 63.
Two by two square Four squares in a block. The corner numbers that face each other are 11 apart and 9 apart. Example on a 1 to 100 chart: 34, 35, 44 and 45.
Zigzag Two short rows that overlap by one square. Under the first top number sits the number 10 more, and to the left of that one is the number 9 more. Example on a 1 to 100 chart: 46, 47, 55 and 56.

Standard pieces (5 or 6 squares) 9

Column of five Five squares straight down. Every number ends in the same digit, which is what counting by tens looks like. Example on a 1 to 100 chart: 8, 18, 28, 38 and 48.
Letter F A column of three with one square sticking out at the top right and one at the middle left. Example on a 1 to 100 chart: 72, 73, 81, 82 and 92.
Letter U Two posts joined along the bottom. The two top numbers are 2 apart with a gap between them. Example on a 1 to 100 chart: 57, 59, 67, 68 and 69.
Letter Z A short row, a column through the middle and another short row. Top left to bottom right is a jump of 22. Example on a 1 to 100 chart: 25, 26, 36, 46 and 47.
Long L Four squares down the column, then one to the right: three jumps of 10 and one jump of 1. Example on a 1 to 100 chart: 41, 51, 61, 71 and 72.
Plus sign A middle number with its four neighbors: 10 less above, 1 less and 1 more beside, 10 more below. Example on a 1 to 100 chart: 35, 44, 45, 46 and 55.
Staircase Steps that go down, right, down, right. The numbers on the corners of the steps are 11 apart. Example on a 1 to 100 chart: 13, 23, 24, 34 and 35.
Tall T A row of three on top and a stem of two below the middle square, counting on by tens. Example on a 1 to 100 chart: 66, 67, 68, 77 and 87.
Two by three block Two full rows of three, one on top of the other. Each bottom number is 10 more than the one above. Example on a 1 to 100 chart: 63, 64, 65, 73, 74 and 75.

Challenge pieces (7 to 9 squares) 6

Big corner Four squares down, then three more along the bottom row: jumps of 10 first, then jumps of 1. Example on a 1 to 100 chart: 5, 15, 25, 35, 36, 37 and 38.
Big plus A row of five crossed by a column of five. The center number is 2 less, 2 more, 20 less and 20 more than the four tips. Example on a 1 to 100 chart: 25, 35, 43, 44, 45, 46, 47, 55 and 65.
Letter H Two columns of three joined by one square in the middle row. Example on a 1 to 100 chart: 72, 74, 82, 83, 84, 92 and 94.
Long staircase Seven squares going down and right in turn. Each full step, one down and one right, adds 11. Example on a 1 to 100 chart: 31, 41, 42, 52, 53, 63 and 64.
Picture frame A three by three block with the middle cut out, so there is no center number to lean on. Example on a 1 to 100 chart: 16, 17, 18, 26, 28, 36, 37 and 38.
Three by three block Nine squares. The middle number is the average of any two squares that face each other across it. Example on a 1 to 100 chart: 44, 45, 46, 54, 55, 56, 64, 65 and 66.

How this list was compiled: Own work. The 22 piece shapes were drawn for this site on 2026-09-18. Every shape is one connected piece that can be cut from a chart 10 squares wide, no two shapes are the same, and the example numbers in each line were worked out from the chart layout (one square right is 1 more, one square down is 10 more) and checked a second time. Prime counts used in the page copy were computed the same day; the sieve method was checked against https://en.wikipedia.org/wiki/Sieve_of_Eratosthenes on 2026-09-18. Licence: own work

How a puzzle piece works

Take a plus-shaped piece with 45 in the middle: 35 sits above, 44 and 46 beside it, 55 below. Down and right adds 11, down and left adds 9.

Filled, blank and partly blank charts

Under Show the numbers, choose Filled in, Blank or Partly blank. For a hundreds chart poster, press Print the chart for the filled chart on one Letter or A4 page. The tool makes no larger poster.

Mark the multiples and round to the nearest ten

Open More options and press up to 4 numbers under Mark the multiples of. For a rounding hundreds chart, press 10. The tool has no rounding view. On 1 to 100, numbers ending in 5 to 9 round up to the ten that ends their row.

On a printed chart, cross out 1 and each multiple of 2, 3, 5 and 7 except those four. The 25 left are primes.
Slip printed pieces into a dry-erase pocket, and one page of pieces serves a math station all week.
For a child who is stuck, ask one question: along the row or down the column? Then count on by 1 or by 10.

Questions and answers

What is a hundreds chart puzzle?

It is a piece of a hundreds chart with one number filled in and the other squares blank. The solver works out each missing number from where its square sits: 1 less to the left, 10 less above. It practices place value.

Should I use 1 to 100, 0 to 99 or 1 to 120?

Match the chart on your wall, and pick it under Numbers on the chart. 1 to 100 is the chart most classrooms have. 0 to 99 keeps each decade, such as 40 to 49, in one row. 1 to 120 adds two rows past 100.

How does a hundreds chart help with rounding?

It shows rounding as a distance. From 47, 50 is 3 squares ahead and 40 is 7 back, so 47 rounds to 50. Numbers ending in 5 sit halfway and round up. Under More options, mark the multiples of 10 to tint the tens.

Which puzzle pieces are easiest?

The 7 shortest shapes, with 3 or 4 squares. A piece along a row is easier than one down a column, because counting by 1 comes before counting by 10. Shapes are dealt at random, so press New puzzle piece until a short one appears.
