Printable number line to 100

The unnumbered ticks are drawn shorter, exactly as they are on a ruler, so counting between two printed numbers is possible rather than guesswork. That is the skill this line is actually for: finding 68 on a line marked at 65 and 70 is reading a scale, and it is the same thing a child will later do with a measuring jug and a thermometer.

Three strips rather than six, because a line to 100 is a reference to keep rather than something to cut up for a table of children. If a different interval is wanted — every 2 for even numbers, every 10 for rounding — the sheet is one control away in the builder, and the ticks move with it.

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.
