This is a fantastic project! It is easy to follow, with no art skills required for the instructor. The teacher doesn't even have to draw. See the 4th grade student example for an idea of how younger students might do.
Note: The last two pages of the PowerPoint are printable student practice pages.
Students can create beautiful artwork by following along with the PowerPoint presentation. Presentation includes practice pages for drawing tulips for students to use with the printable handouts, examples of color combination choices, and written instructions for each step of the project along with a picture of how to do it.
Art supplies required for this project are as follows: green construction paper, blue and green crayons (peeled and broken into 4 pieces each), oil pastels, scratch paper to cover work to avoid smudging, and sealant (either Mod Podge or spray sealant).
I recommend using matte Mod Podge and having a parent volunteer or trustworthy student paint each picture to seal them. Two or three students can share a set of oil pastels and crayons.
I recommend handing out the tulip-drawing practice pages(from the end of the PowerPoint) ahead of time for morning work or another convenient time. Giving the students a little time to practice will really help them do well on the project. If given out a day ahead, many students will practice over and over.
I also recommend providing clean paper for students to place over their drawings while they work on other areas. This will help reduce smudging.
