30 Famous Painting Cards
We enjoyed recreating Monet's Japanese Footbridge painting.
We used masking tape to make the bridge and painted all around it.
Once the painting is dry, peel it off and it leaves a white bridge behind.
The Denver Art Museum has some very fun ideas in their Monet's Magical Garden lesson plan- it is geared towards very young children with fun interactive ideas.
Another really fun resource is the movie Linnea in Monet's Garden- it a book that has been made into a DVD. The movie is available on Netflix if you subscribe to it. You can also get the book or movie on Amazon.
