Collaboration - Elementary School Art Auction Pieces

This is the Kindergarten Classes Collaborative Piece 22"x17"

On top of the individual and collage art auction pieces I've created a collaboration piece for each individual class. My collaboration pieces are a mosaic puzzle of an image. Here are my steps:

1) I created the piece on an 8.5x11 piece of paper with just the outlines (like a coloring book page.) 
2) I then blew it up on a copier so that it became a 22" by 17" piece.
3) Using oil pastels, I matched the colors to the original inspirational painting.
4) I cut it into squares depending on the number of students in my class. (16 or 24)
5) I laminated the squares individually.
6) In a plastic bag I put the the individual laminated square, and the identical uncolored square, plus the oil pastels used to color in that specific part.
7) I know my students abilities so I made sure to match the artist skill to the complexity of the square.
8) I'll spray a fixitive on top and mount them together to create a single piece.

Kindergarten Art Auction Piece

This is a collage piece.
Each student has a flower in this
bouquet. One student is the vase. 

Since my kindergarten class has 22 students I'm going to have four bouquets of flowers to assure each student has a flower in the auction. I chose four student's vases that best fit the flower colors.

I created four different flowers for the kids to watercolor paint. I wanted consistency with the design and have the kids really focus on the painting part and not the drawing part. The first week of painting I had them add some crayon resistance to outline or add design to the flowers. The second week of painting I had them just use watercolor and no crayon. I think they were more successful when they had the crayons.

I gave them outlines for three different vases. This time I brought in acrylic (not tempura) paint for them. They used cotton swabs to mix the paint and apply it. I like using cotton swabs to paint with kindergartners better than paint brushes, they fit their small hands better and don't rely as much on fine motor skills.

I will be assembling the four collages for the art auction and watch the 7-8 families enjoy a healthy battle to win the piece. I'll post all of the final art pieces for the auction after I've mounted them.
