1. Under Numbers, choose the range you want: 1 to 100, 0 to 99, 1 to 120 (12 rows), 101 to 200, or Another hundred.
2. Under Start at, pick a later hundred if you want the chart to begin past the first one.
3. Under Style, choose Filled chart, Blank grid, Fill in the missing numbers, Shade a skip-counting pattern or Puzzle pieces.
4. If you chose Fill in the missing numbers, set How many squares are blank to about a quarter, about half or about three quarters.
5. If you chose Shade a skip-counting pattern, set Shade the multiples of to a number from 2 to 10.
6. Under Shading, keep Light grey (printer-friendly) or choose Light color.
7. If you chose Puzzle pieces, set Pieces to 6, 9 or 12.
8. Type a name in Title on the sheet if you want something other than Hundreds Chart.
9. Leave Include answer key checked to print the answers on a separate page, or uncheck it.
10. Set the paper size to US Letter or A4, then select Print or save as PDF.

What is a hundreds chart?

A hundreds chart is a grid of numbers, usually 1 to 100, with ten numbers in each row. Every chart is built by counting up one square at a time from the starting number, ten to a row, so the first row holds 1 to 10 and the second holds 11 to 20. A 1 to 120 chart works the same way with 12 rows, and the last row holds 111 to 120.

How do you use a hundreds chart?

You use a hundreds chart by moving across it, because every move means something. One square down is ten more, and one square up is ten less. Diagonals follow the same logic: down and to the right is eleven more, and down and to the left is nine more. Ask children to start on 23 and move down-right three times. They land on 34, 45 and 56, which shows them how to add tens and eleven without counting from 1.

Shading multiples turns the chart into a picture of multiplication. Multiples of 10 make a single column down one edge, and multiples of 5 make two columns. Multiples of 2 fill every other column. Multiples of 3 and 9 run in slanted lines, because 3 and 9 do not divide evenly into 10. Print two shaded charts, such as multiples of 2 and multiples of 3, and ask which numbers are shaded on both. Those are the multiples of 6.

What is a hundreds chart puzzle?

A hundreds chart puzzle is an activity where children find, fill or rebuild numbers using the grid’s patterns. Children might fill in missing numbers, or rebuild a chart from pieces. In a clue game, you might say, “My number is one row below 35 and two squares to the left.” The answer is 43, and the first child to name it gives the next clue.

Puzzle pieces are the pencil-and-paper version of the same idea, and they are harder because only one number in each piece is given. For a hands-on version, print a filled chart on card stock, cut it along the grid lines, and have children rebuild it. On a filled chart, children can also cover a few numbers with counters while a partner names each hidden number and lifts the counter to check.

Can I print a 120 chart?

Yes. Choose 1 to 120 (12 rows) under Numbers, pick a style, and select Print or save as PDF. A 120 chart is useful once children are comfortable with 1 to 100, because the extra two rows let them practice counting past 100 in a familiar layout. For first grade, a filled 1 to 120 chart, or one with missing numbers, can help with understanding tens, and shading multiples of 10 makes the tens easy to see.

Can I print a blank hundreds chart?

Yes. Choose Blank grid to print an empty ten-column grid that children fill in from memory. For a partly blank chart, choose Fill in the missing numbers and set how many squares are blank. Both styles come with an answer key on a separate page, and the key for either style is the full chart. Press New worksheet to get a different set of blanks with the same settings.
