I am so excited that I found a new clip art site for teachers. You can use their clip art for all of your teacher creations both personal and commercial. There are over 45,000 quality clip art pieces to take advantage of! There are no annoying ads that make you click away to another page to sign up for additional clip art. All of the clip art is right on the page. Take a peek at WP Clipart at http://www.wpclipart.com!
Here are a few examples of what they have:
Positive Word Clip Art
Owl Clip Art
