Recycled Cookie Sheet for Groups - Green Theme Day 2

So here it is, my upcycled cookie sheet. :) I had seen how you could use cookie sheets in the classroom on Pinterest since they're great with magnets, so I was super happy when I got my hands on an old one at Goodwill the other day.

What I Did:
1) Washed it of course
2) Primed it white
3) Added masking taped strips evenly
4) Painted the lines without tape with acrylic green and let dry
5) Removed the tape and airbrushed the rest a light mint green color
6) Designed four large circles on the computer using JW Illustrations HippieChic Papers (I made sure to take measurements. My circles are split through the middle because I teach two classes - my homeroom (Carro) and my partner teacher's homeroom (Greenleaf). Hence all the Cs and Gs.
7) I also created numbers 1 through 4 for my four different science groups. I pasted them onto the board and then added Mod Podge - BIG MISTAKE! I still keep trying to use Mod Podge on copying paper. It always wrinkles it. I need to remember to use card stock.
8) Made Avery labels for each student's number and stuck them to thin water bottle caps.
9) Attached magnets to the opposite sides and now I've got changeable grouping!

I do science groups, so I'll be using this for that. I attached the cookie sheet to one of my metal doors using strong circle magnets.

 Stay tuned. More green theme stuff to come!
