This file included three numbers lines that can be printed on 3"x24" sentence strips. There are three different types of number lines - an open number line, one with just dots, and one with dots and numbers up to 22. If you laminate these they can be used over and over. If you'd like a specific style of number line please let me know!
How to print: Create a custom paper size of 3x24. Open number line file you would like to print and choose the custom paper size. Depending on your program you can sometimes zoom in on the number line to eliminate extra margin space.
Added 8/15/14: Two more versions! One up to 10 and one up to 30.
