I use 2 main books to teach art.
How to Teach Art to Children - Evan-Moor Publishers (for grades 1-6) and
Meet the Masterpieces: Strategies, Activities, and Posters to Explore Great Works of Art - Scholastic (for grades 2-5)
(I cannot find an online pic I can show you, but here is the amazon page - Amazon.com book page (It's apparently out of print now, but well worth finding if you can.)
Last year, we studied Line, Shape, and Color from the Evan-Moor book and Pieter Bruegel, Diego Velasquez, and Hokusai from the Scholastic book.
This year we will study Value, Texture, Form, and Space, as well as study the following artists: Winslow Homer, Pierre Auguste Renoir, Mary Cassatt, Pablo Picasso, and Romare Bearden.
I planned 83 art lessons. We do art nearly every day, but since we are adding history this year, I think there will be days when we do art in history or science and won't do it separately too. I schedule Art right after Bible, so it is our second subject of the day. I find that it helps the kids get "into" school and gets their creativity flowing, which in turn helps them academically. Also I can get the "together" work out of the way first and then they can do their independent work later, rather than me trying to gather everyone back at a later time, when someone might be in the middle of an important assignment.
The Evan-Moor book has two parts. Part 1 is the main section of the book. It includes the art lessons that are about Value, Texture, Form, and Space all are introducing an art concept to the children. Each lesson has either an art project or a small group experience to reinforce the concept. The art projects in this book are particularly eye-catching and attractive, in my opinion.
Part 2 is all art projects based on a famous artist, such as Edward Degas, or a famous art technique, such as Anasazi pottery. I have sprinkled these 24 lessons throughout the year, so we get a break from the normal routine. I also found examples of each of these famous works or techniques online and saved them to my hard drive, so I can show the children some examples when it's time for that lesson. No more jumping online while they wait, colored pencils in hand.
After every section from the Evan-Moor book, I have scheduled a section from Meet the Masterpieces. This book has a short section on the artist's life, which will be our Day 1 of that section. We will add the artist to our main timeline and find out more about him/her if we so desire. On Day 2, we take a close look at one of the artist's works. The book gives some excellent questions to ask the students about the work, and even gives you the answers, which is great for those of us who did not study much great art. (Apparently this book originally came with posters of these works, but I do not have those. Therefore, I searched the internet for copies of the works and printed them out. I put them in my lesson plan binder, along with my lesson sheets for art and I'm all set!)
For Days 3-5 of these lessons, the book has differing activities that build on the concepts learned about the artist and/or the time period. Some of these I like, and some I don't, but I have chosen the ones I want to do and listed them on my plan sheet.
Something else I did to make all this easier was to list out all the supplies needed for each lesson, so I can quickly look ahead and make sure I have the 12x18 white paper that is needed, or stop at the store for dried beans.
I think Suzy and James will be doing art with us most days this year and I am looking forward to something else that we can all do together!
If you do not schedule art regularly, I encourage you to do it. It has made a big difference in our homeschooling!
