For Teachers
Maths, science and design-tech grids for classroom photocopying.
Who this collection is for
Teachers need grids that photocopy cleanly onto a school printer, in formats students recognise from their textbooks. The 5 mm and 10 mm cross-section grids, polar coordinate sheets and isometric dot grids on this page cover the maths, science and design-and-technology curricula in most national education systems. Recommended reading: A reading list of essential references can complement these grids.
Why curated grids matter
Every discipline reaches for a slightly different palette of printable paper. The wrong grid can quietly distort a sketch - too dense for the brief, too sparse for the detail, calibrated to a scale you don't actually use. This page gathers the 6 grids most-used by working for teachers practitioners, with the standards and history behind each one. Read first: How to print at exactly 1:1 before printing anything that needs to be measured.
