Questions about the Fraction Rules poster

Who is the Fraction Rules poster for?
Fraction Rules is filed under 5th Grade (ages 10–11), 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 Fraction Rules poster?
The single-sheet summary of the six fraction posters in this set. A wall chart earns its place by being glanceable from where the work is happening, so Fraction Rules belongs on the wall where that math work actually happens, within glancing distance, rather than filed away.
What other posters go with Fraction Rules?
Adding Unlike Fractions, Area & Perimeter and Sorting Shapes by Their Properties sit alongside Fraction Rules in the 5th Grade set. Printed together they make a wall rather than a single sheet, which is how a reference set actually gets used.Adding Unlike FractionsArea & PerimeterSorting Shapes by Their Properties
Is the Fraction Rules poster free to download and print?
Yes. Fraction Rules downloads as a free PDF with no account, no email and no watermark, like everything else in the 5th 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 Fraction Rules poster print at?
Fraction Rules 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 Fraction Rules loses nothing.Printing guide
