Hi Gloria,
There are two ways to do that.

Either use the little "traffic Light" in the object manager (the top light is for editor view, and the lower one is for rendering. If you use both, the non-render/show option will win, none allows to be overwritten to render.
The traffic lights can be click or "painted" if you like to click and drag. Option Click changes both. BTW, gray means, it uses the parent setting.
OR use Layers (Layer Manager); the R column allows for managing those.
Please have a look here:
