Box 1 version of Freight Train, by Donald Crews

For children under 2, it's best to use this as a suggestion for how adults can present the Box 1 stringed balls as a puppet show, rather than to use it as a movie for them to watch. The oral storytelling aspect is a valuable addition to reading picture books - both before the child has seen and heard the book, and afterwards. Quoting books the child knows while away from the book itself brings art to life. 

For children age 3-6, this movie is an introduction to how literature can be presented in a different medium. It also subtly shows an attentive audience, who each see themselves reflected in the theatrical production. Teachers might also find it useful to discuss how the "audience" are seated in an order conducive to appropriate behavior - because red is next to orange, it's easier to be quietly attentive, rather than the bright high contrast of red next to purple, even though red and purple are good friends who like each other very much!

Finally, this was VERY easy to make, using the video function of my iPhone. Parents and teachers could make a version featuring their own voices, or a child's voice. I'm planning to record this again for YouTube, with a native Spanish speaker, and in other languages as I find native speakers of German, Mandarin, etc.
