A 1–100 grid to count on, color on-screen, and print — filled for reference, blank for writing practice, with missing numbers for a challenge, or extended to 120.

Hundred chart
What a hundred chart is for
The chart turns numbers into a landscape: down a column adds ten, along a row adds one, and skip-counting paints stripes a child can see before they can explain them. Highlight the 2s or the 5s and let the pattern do the teaching.
The missing-number variant makes a quiet worksheet — fill the gaps from the neighbors. The blank grid is the hardest and the best: writing 1 to 100 from memory is a complete tour of two-digit structure. The diagonals hide a move worth naming: down-right is plus eleven, up-right is minus nine, and a child who sees that stops counting on to find them.
A hundred chart lays 1 to 100 out in ten rows of ten, turning number relationships into positions: down a column adds ten, across a row adds one, and multiples form visible stripes. It suits the counting stage — Foundation on our nine-level ladder — where children are still building the sense of order and place value that abacus work then formalises.
Which version should I print — filled, blank, or missing numbers?+
Filled is a reference to count along; blank is write-in practice and the hardest of the three, since writing 1 to 100 from memory covers the whole two-digit structure; missing numbers hides about a third of the cells for a fill-in worksheet. A 1-120 grid is also there for counting past one hundred. All four print from the same page.
How do I use it to teach skip counting?+
Tap the 2, 3, 5 or 10 chip and every multiple lights up at once, so the pattern appears as columns or diagonals rather than as a list to memorise. One count is active at a time, so children compare patterns by switching between them. Any individual cell can also be toggled by hand for odd/even work or a number hunt.
Does the missing-number sheet change every time I print it?+
No. The hidden cells come from a fixed seed, so the same sheet prints today, next term, and on any device — a class set stays identical and an answer given last week still matches. Printing is free, needs no account, and the Print button strips the site chrome so only the title and the grid reach the paper.
