Who is the Adding one poster for?

When should you use the Adding one poster?

Is the Adding one poster free to download and print?
Yes. Adding one 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 Adding one poster print at?
Adding one 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 Adding one loses nothing.Printing guide
