Over all, my kindergarten classes did very well with painting their pumpkins & mixing orange. Every year is so different...sometimes every class is so different!! ha ha The image is 12in x 18in....I like kindergarten to have a large space to paint on. Painting has enough issues for kindergarten....you really don't want them to work in small spaces!! ha ha I use the biggy paints...4 colors. They did great keeping the colors clean as well. May need to paint a bit more since I feel pretty confident with their skills!!!
