Art needs to be approached as a multi-media subject.
If you are just teaching drawing allow each student to have multiple pencils so they feel comfortable about not breaking or losing it. Let them have some unsharpened to play and figit with while they are working. If using charcoal or other messy material, provide an abundant supply of cleaning wipes and perhaps a work apron or shirt.
Use a large sheet of paper on an easel to demonstrate what you want them to do. Explain you are showing an example, their work might differ. Allow them to stop every 10 or 15 minutes if they want to.
Have a finished project available for them to see what is expected.
Work with one at a time, and ask the others to help by drawing their work at the same time.
Personally, we have art time which includes a variety of colored paper, fabric, glue, lace, and various other craft items. They are free to use what they want to create a project. I also have charts showing various art concepts, such as color wheel, perspective, space shape.
