Questions about the Number Line 0–20 poster

Who is the Number Line 0–20 poster for?
Number Line 0–20 is filed under 1st Grade (ages 6–7), so it matches what that year asks a child to remember. It is equally useful to an older student revisiting math, and to the parent or teacher answering the question at the kitchen table.
When should you use the Number Line 0–20 poster?
Count on from the bigger number — the arrows show the move. A wall chart earns its place by being glanceable from where the work is happening, so Number Line 0–20 belongs on the wall where that math work actually happens, within glancing distance, rather than filed away.
What other posters go with Number Line 0–20?
3D Shapes, Adding zero and Adding one sit alongside Number Line 0–20 in the 1st Grade set. Printed together they make a wall rather than a single sheet, which is how a reference set actually gets used.3D ShapesAdding zeroAdding one
Is the Number Line 0–20 poster free to download and print?
Yes. Number Line 0–20 downloads as a free PDF with no account, no email and no watermark, like everything else in the 1st Grade set. Print as many copies as you like for a home, a classroom, a library or a tutoring group; reselling the file is the only thing the licence rules out.Read the licence
What size does the Number Line 0–20 poster print at?
Number Line 0–20 is a vector PDF laid out for US Letter, and prints on A4 with Fit to page — the same file, no separate download. Because every mark on it is drawn rather than photographed, it stays sharp enlarged to A3, A2 or A1 at a copy shop. Colour carries emphasis only, so a greyscale print of Number Line 0–20 loses nothing.Printing guide
