The first step in improving students' own artwork is helping them SEE! Use this observation worksheet with your students to help them visually break down visual elements in any subject matter.
Help your students recognize and record line, color, shape, and texture. Choose what to observe! It can be artwork, nature, animals, buildings, fashion, ANYTHING!
Observation is very important for your elementary artists, so this is an important foundation in their skill set. I encourage you to use this as early as 1st grade.
Have fun observing the amazing world around you!
