I use Linnea in Monet's garden with the 3rd Grade and it has worked well for us. I have Monet prints on each table and we talk about them briefly before watching the video. They enjoy identifying those scenes in the video. They also enjoy comparing photographs, painting and the cartooning of the video.
The video is slow in comparison with today's fast paced images of television, movies and computerized imagery, but I feel it causes the children to look longer and differently at the work. They don't seem to be bothered by the the relationship between Linnea and Mr. Bloom as they seem to see it as a grandfather/granddaughter sort of friendship.
I like how the video explains visiting an art museum and impressionism.
For our project, we do a watercolor wash with cool colors. Then we use tissue paper to make water lilies, turtles, frogs, stones, fish, flowers, people, etc. Finally we paint mod podge over the entire work. It has been a successful project with some beautiful results. I just finished this project this week and noticed that students were adding the title to their artwork---"Mary's Garden" ----after themselves.
The Venezia videos about Monet and van Gogh are good, too. They are fast paced, informative and funny. Perhaps the use of these videos depends not only on the grade, but the personality of the class.
