My 3rd-5th grade group finished painting their dream art studios.  A lot of creativity went into these, and the results are really fun to look at.  This was a long, detailed project.  And, as much as they enjoyed it, I think some lost steam toward the end.  Students in this group beg for this type of project, so I occasionally include them.  However, I know their ambitious ideas are sometimes difficult to execute.  I am still quite pleased with the results.  I think the kids were too, and that is really all that matters. : )
