iRubric: Skull and VALUE rubric

Student matched values for each hue. The artist has a very large range of values in their piece. Correctly placed and matched values within shadows. Used eraser tools to grab highlights and glares and shaded in value throughout almost the entire piece. Student has matched textures and used the blending tool or their finger to blend.

Student matched almost all the values and has a semi-wide range of values in their piece. Some of the values are a little off either too dark or too light. Texture is done pretty well. Student could have benefited from a little more use of the blender stump and/or eraser stick.

Student has a limited range of values and has quite a few values shaded in, incorrectly. Texture looks rushed and pencil marks when shading are still pretty visible.

Student has a very limited range of values and isn’t correctly shading the values seen. Student rushed through this process and has very rough-scratchy texture because of shading.

The artist framed and used lines of symmetry in accurate positions with logical numbers.They did all of this ON THEIR OWN without any guidance. They were capable of creating a congruent frame and lines of symmetry on their drawing paper as well.

Student created the frame and guidelines correctly, but may have needed some assistance or traced the frame and guidelines on drawing paper. Student could have maybe picked a more logical number and/or setup.

Student drew the frames and lines of symmetry, but they might not have matched up correct, student may have traced them, and/or needed much assistance.

Student does not have frame or lines of symmetry on BOTH pieces.
