And here are some snippets of conversation from our drawing sessions:
"Yellow train. One on the train, the line is the one. There's a rainbow! Now a purple train," Bowen announced as she added different layers of color to her drawing.
"It's the Number A train," Juliet decided. "The 2 train. It's going away to pick more people up."
Samuel said, "The subway, I'm making. The train station. It's a green train. I'm making my train as a rainbow. My one will be a rainbow train."
As soon as we sat down, Joseph said, "I want to make the subway!" Olli watched him work and was eager for his own turn. As soon as he grabbed his paper, he shouted, "CHOO CHOO!"
"I'm going to draw the purple train. It's leaving," Zara said.
Angelo decided, "The train is going to the police."
And Dylan said "I'm going to draw the blue one. I'm riding the subway. The yellow is the D train."
