This is a simple integer number line set. On the first line are the numbers 0 to 60 (by 2). The second line are the numbers -30 to 30 (by 2). On the last line are the numbers -60 to 0 (by 2). There are many number-line generators out there, but all want to do one type of line multiple times, so I just created my own and thought it would be good to share!
