I made this 1 cm grid paper because those blue lines on commercial graph paper just don't photocopy. When my school runs out, that's it. Well no more! These pages contain centimeter graph paper that's easily accessible from a school computer.
This product contains 19 x 25 centimeter boxes. I have included 2 pages, one in easy to see, easy to reproduce black. The second has light grey lines in case you need student work to stand out more.
