Deep Space Sparkle. I did this with grade 2's, and it took us two periods of an hour to finish.
Day one: Students drew the giraffes. I gave them techniques for how to do different movements with the giraffe. They then colored them in marker, and cut them out. Most were able to finish this entire step within the first hour.
Day two: On the second day, students painted the background using tempera paints. They added a silver moon, and some chose to add sparkles. They then glued the giraffes to the paper. A super easy and adorable lesson!
