It's just an inch. 0 to 1 in the form of a ruler. Printable handout to give to students to use as a guide for what all the little marks mean between 0 and 1 inch.
In my class we label all parts of the inch in their fractional way and we talk about equivalent fractions and what 1/8 1/16 and 1/2 are.
Then when we measure things around the room they can use this page as a guide for identifying which fraction of an inch they are looking at.
Print on yellow paper to give it that old fashioned ruler look.
