About the printable number lines
The number line is where arithmetic becomes movement: addition is hopping right, subtraction is hopping left, and the "counting on" strategy suddenly has somewhere to happen. Six identical 0–20 lines on one page means one problem per line — model 8+5 on the first, 13−6 on the next — or cut the page into strips so every child gets their own. The 0–20 range matches K–2 fact work exactly.
Frequently asked questions
How do children use a number line?
Start on the first number and hop: forward to add, back to subtract, counting each hop aloud. Drawing the hops keeps the strategy visible.
Why six lines on one page?
One line per problem. Work down the page for a set of problems, or cut the sheet into strips for individual desk number lines.
Do you have other ranges?
Yes — a blank number line for custom ranges is available, and the generator roadmap includes 0–100 and negative-number lines.
