When should you use the Odd and Even poster?
Get a handful of counters and try to pair them all up. Leftover means odd. A wall chart earns its place by being glanceable from where the work is happening, so Odd and Even belongs on the wall where that math work actually happens, within glancing distance, rather than filed away.

Yes. Odd and Even 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 Odd and Even poster print at?
Odd and Even is a vector PDF laid out for US Letter, and prints on A4 with Fit to page — the same file, no separate download.

Colour carries emphasis only, so a greyscale print of Odd and Even loses nothing.Printing guide
