My coach showed me this website which has good basic resources. For free, you can get blank graphs, number lines, and worksheets on integer arithmetic or telling clock time. You can also subscribe and get access to a whole bunch more stuff that I can't tell you about.
The site is designed for early ed, but I use everything I listed above in my 9th and 10th grade classes as well when kids are struggling with their basics. You can choose (to some extent) what kinds of features you want included in your worksheet. So it's a little DYO but still very simple and straightforward.
