Matisse for Kids. It teaches about the artist, Henri Matisse, in a fun way. Kids can "earn" colours, patterns and props used by Matisse in his art work by, for example, correctly identifying elements in his paintings. They slowly add to their portfolios, and at the end of the tour of his works, get to create a Matisse-style work of their own. You can see mine at left.
I really like the balance in this "game" between learning and creating. I learnt a lot about Matisse and I think your kids will too. It's a great activity to do before or even after a visit to an art gallery showing some of Matisse's works.
If you're taking your kids to an art gallery, be sure to read At the Art Gallery, an article by Jeanne of A Peaceful Day in Literacy Lava 7 with tips to help your kids get the most from their visit. All 9 issues of Literacy Lava are still free to download as pdf's at my website.
