Printable hundred chart

The chart is worth having on a wall before it is worth being a worksheet. A child who is asked “what is 34 and 10?” and can put a finger on 34 and move it straight down has been shown something a right answer would not have given them: that the tens digit is the row and the units digit is the column, and that adding ten is a move rather than a sum.

Print the blank one beside it and the pair does most of Grade 1. Counting in twos, fives and tens are three patterns a child can color in; the multiples of nine come out as a diagonal; and the numbers that will not make a rectangle of counters — the primes — are the ones with nothing shaded around them.

Every line on the page above is drawn as ink rather than as a background, which is why it comes out of the printer looking like it does on screen: browsers throw background color away unless somebody has ticked Background graphics, and a chart printed as a set of empty boxes is worse than no chart. The lengths are in inches for the same sort of reason — a square that says it is three quarters of an inch is three quarters of an inch, because a child measuring against it will find out if it isn’t. The number in the footer is the seed the sheet was built from, so the identical sheet can be had again next week.

This page is one sheet out of a family that prints four: a hundred chart, a number line, a coordinate grid and a place-value chart. The range, the interval, how far the axes run and which places the columns hold are all settings — so a number line every 2 to 30, or a chart from 101 to 200, is the same sheet with one control moved rather than a page somebody has to have written first.

The settings travel in the link rather than on a server, so a sheet you make can be bookmarked or sent to another family as it stands — and the Name: line, where a sheet has one, is printed blank, because there is nowhere in a shared link to put a child’s name. See what we don’t collect.

A multiplication grid — blank to fill in, with the completed twelve-by-twelve square on the page behind it — is on the math shelf, because it is the times-table family with the grid switched on rather than a chart of its own. Squared, dotted and isometric paper is on the paper shelf, where everything comes on both Letter and A4: a quarter-inch square scaled to fit whatever was in the tray is no longer a quarter-inch square.
