Hundred Chart
The 1-100 grid that quietly runs kindergarten through second grade: skip-counting, plus-one and plus-ten patterns, missing numbers, mystery clues. Print the chart — the notes below are the games that keep it in use all year.

A number line, folded into a grid
A hundred chart is the counting sequence arranged ten to a row, which means it is secretly two tools at once: read across for the number line, read down for the tens. Move one square right and you have added one; move one square down and you have added ten. That second fact — that the number below is always ten more — is the chart's superpower, and it is the mental-math habit place value is built on.
The chart earns its year-long wall spot through games rather than drills. Skip-count coloring (color every second number, watch the columns emerge) teaches the 2s pattern without a times table in sight. Missing-number puzzles — a chart with holes — turn writing numbers into detective work. And mystery-number clues ("I am more than 40, less than 60, and my digits add to 10") hit number sense, inequality and addition in one five-minute warm-up.
Teaching tips
Color the skip counts
Every 2nd number, every 5th, every 10th — each with its own color. The columns that emerge are the multiplication patterns kids will meet in grade 3, learned here as pictures first.
The 10-more box
Point anywhere and ask "ten more?" — the answer is directly below. Then "ten less" (above). This single habit, repeated for a semester, is regrouping rehearsal without the column arithmetic.
Hole-punch a copy
White out a dozen numbers on a printed copy and kids fill the holes. Holes near row-ends (48→52 across a decade boundary) are the ones worth leaving.
Count by ones first, always
Before any pattern work, a new-to-the-chart child should read a full row aloud. The chart assumes the sequence; the sequence comes first.
Frequently asked questions
What is a hundred chart?
A 10×10 grid of the numbers 1-100, ten per row. Reading across gives the counting sequence; reading down adds ten each row — which makes it a tool for skip counting, place value patterns, and one-more/ten-more mental math.
Why do some hundred charts go 0-99 instead of 1-100?
Both layouts exist. A 0-99 chart lines up the decades in columns (every row starts a new ten); the 1-100 chart is the more common K-2 version in the US and matches how the counting sequence is said aloud. Either teaches the same patterns — match whichever version the school uses.
What grade uses a hundred chart?
Mainly K-2: counting and number recognition in kindergarten, plus-one/plus-ten patterns in grade 1, and skip counting in grade 2. It fades out in grade 3 as the multiplication chart takes over the same wall hook.
How is a hundred chart different from a number line?
Same numbers, different shape — and shape is the feature. A number line shows magnitude as distance; a hundred chart folds that line into rows so same-tens numbers stack into columns, making +10 a physical move downward.
