Second week: School wide recycled cardboard releif

Here's how my brain works:

I need a project for our yearly county-wide recycled art contest.... I need a project that includes everyone, unlike last year where I waited too long and could only get my kinders and 3rd graders done in time...I have 585 students, how am I going to get them all involved???!!!....Aha, thank you, Google images!......Here we go!

My students are now spending 1 class period and learning about reliefs by cutting out and painting 1 piece of cardboard that will then be assembled to create a giant school-wide relief sculpture.
