Living Art Lessons Artist's Set
Learn about the seven elements of art including lines, shapes, and colors, while observing artwork and nature all around you in this complete, easy-to-use, year-long program. The Artist's Journal contains the student's artistic workspace for writing, drawing, and more, all related to the teaching in the main text.
It is designed for grades 4 to 6, but I am sure younger children can be part of most of the lessons. Even older children will learn a lot, especially if they do not have any other art background. You can easily adjust this program to suite your family.
I think a camera to take pictures of scavenger hunts will be useful and it may just be the start of photography as a new hobby/interest for the child (or adult) as well.
Thank you Masterbooks for another great resource!
