### Lesson 9: Inward and Outward Curves (Objects, Position, and Perspective)

Instructors tell children:

- Inward curves are lines that curve inward.
- Outward curves are lines that curve outward.

Instructors show children examples of:

- Inward curves, such as the inside of hats, bowls, or cups.
- Outward curves, such as the outside of an apple, ball, or orange.

Instructors show children the lesson image (scenes A-G), and ask children to point to the following surfaces:

- Horizontal, straight
- Oblique, straight
- Inward curve (2)
- Outward curve (3)

Children complete the following drill work:

- Draw a ball on a horizontal surface.
- Draw a ball on an oblique surface.
- Draw a ball on an inwardly curved surface.
- Draw a ball on an outwardly curved surface.
- Draw a tree on an outwardly curved surface.
