How to use it
- Choose 100 or 120. Kindergarten usually works to 100; first grade to 120.
- Set how much is filled. Full for reference, blank for assessment, or blank out only some cells.
- Shade a pattern. Any step from 2 to 12, which turns the chart into a skip-counting exercise.
- Print. One page, US Letter, with an ink-saver option for class sets.
Who it helps, and when
The hundreds chart is the workhorse of early number sense, and stays useful well past the point where children can count to a hundred reliably.

Common questions
A hundreds chart runs 1–100 in ten rows of ten. A 120 chart adds two more rows, matching the first-grade expectation of counting past a hundred without the pattern breaking.
Enter the numbers you want coloured and the generator shades those cells. Print a blank copy alongside it as the student version.
