The smARTteacher Resource: Value Scale Worksheet - Free Printable

The image you've uploaded is a drawing exercise designed to help practice shading 3D forms (geometric shapes) to give them depth and volume, using light and shadow. The task asks you to:

1. Draw each of the basic 3D forms (Sphere, Cube, Pyramid, Cone, Cylinder) in the left column.
2. Shade them in the middle column to match the shaded examples provided.
3. Then, draw and shade your own version of each shape in the right column ("Now it's your turn").

🔍 Let’s break down what’s happening in the image:

#### ✔ Left Column: "Draw your forms"
- These are line drawings of 5 basic geometric solids:
- Sphere
- Cube
- Pyramid (tetrahedron)
- Cone
- Cylinder

These are unshaded, showing only the outlines.

#### ✔ Middle Column: "Shade your forms"
- These are the same shapes, but now shaded with pencil to create a sense of 3D form.
- Shading techniques include:
- Light source direction: Light appears to come from the top-left.
- Highlights: Bright areas where light hits directly.
- Midtones: Gradual transitions.
- Shadows: Darker areas on opposite sides.
- Cast shadows: Not shown here, but implied by shading.

Examples:
- Sphere: Smooth gradient from light to dark, creating roundness.
- Cube: Flat planes shaded differently based on angle to light; one face in shadow.
- Pyramid: Triangular faces shaded to show depth; one side in shadow.
- Cone: Curved surface shaded gradually; base darker than tip.
- Cylinder: Rounded ends shaded with curves; side shows cylindrical curvature.

#### ❓ Right Column: "Now it's your turn"
- This section is blank — your task is to draw and shade each shape here, matching the style and lighting of the shaded examples.

🎯 How to Solve This Task

You're being asked to replicate the shading from the middle column in the right column.

Here’s how to do it step-by-step:

✔ Step-by-Step Instructions for Each Shape

#### 1. Sphere
- Draw a perfect circle.
- Imagine light coming from the top-left.
- Shade from lightest at the top-left, gradually getting darker toward the bottom-right.
- Use smooth gradients — no hard lines.
- Add a soft shadow near the bottom edge to suggest volume.

#### 2. Cube
- Draw a cube in perspective (e.g., one corner facing you).
- Identify which faces are lit and which are in shadow.
- Top and front-left faces: lighter.
- Back and right faces: darker.
- Use hatching or blending to create tonal variation.
- Keep edges sharp but add softness with shading.

#### 3. Pyramid
- Draw a triangular pyramid (tetrahedron).
- One face should be in full light (top-left), another in shadow.
- Shade the visible faces accordingly.
- The apex should be brightest if lit from above.
- Use graduated tones to suggest depth.

#### 4. Cone
- Draw a cone with circular base and pointed tip.
- Light comes from top-left → tip is bright, side curves into shadow.
- Shade the curved surface smoothly, darkest at the bottom-right.
- Base can have a subtle highlight along the top edge.

#### 5. Cylinder
- Draw a cylinder with oval ends and straight sides.
- Light hits the top and left side → those areas are lighter.
- Bottom and right side go into shadow.
- Use curved shading to follow the cylindrical form.
- Ends should have a highlight on the top edge.

🖋️ Tips for Effective Shading

- Use a range of pencils (e.g., HB, 2B, 4B, 6B) for different tones.
- Blend with a finger, tissue, or blending stump for smooth gradients.
- Start light, then darken gradually.
- Avoid harsh lines unless they’re structural edges.
- Always consider the light source — consistency is key.

✔ Final Answer / What You Should Do

Since this is a drawing task, I can't draw on the image, but here’s what you should do:

> In the "Now it's your turn" column, draw each shape (Sphere, Cube, Pyramid, Cone, Cylinder) and shade them exactly like the examples in the middle column.

Use these principles:
- Light source: Top-left
- Apply value gradients (light → midtone → dark)
- Emphasize form and volume through shading
- Match the style and tone of the shaded examples

🧠 Summary

| Shape | Key Shading Tip |
|----------|------------------|
| Sphere | Smooth gradient from light to dark |
| Cube | Flat planes with distinct values |
| Pyramid | Highlight on top face, shadow on back |
| Cone | Curve shading from tip to base |
| Cylinder | Round shading with highlights on top edge |

✔ Once completed, your right-hand column should look very similar to the shaded examples — just drawn by you!
