One of my colleagues has been holding onto a resource for years called "It's My Zoo." This activity, from Teacher Created Resources, is a great time killer / critical thinking activity that students enjoy doing. The activity asks students to design the layout of a zoo following certain pre-set rules. The students can do these zoos either on a sheet of butcher paper, or in 3D using boxes, scraps, etc. I am sorry to say that I neglected to photograph my students finished zoos, but they did come out great and I was excited with the work they produced.
To sum all this up, I decided that the document we've been copying from was getting pretty rough. It was a copy of a copy of a copy or something like that, and was showing its age. So I updated it.

The activity comes with an instruction sheet, a teacher scoring rubric, and animals cards. Enjoy!
