3. The writing board of claim 2, wherein each of the plurality of ribs continuously extend in the lengthwise direction or the widthwise direction from a first end of the substrate to a second end of the substrate opposite the first end to form a plurality of cavities that each extend from the first end to the second end.

4. The writing board of claim 1, further including a film affixed to at least one of the front or rear panels of the substrate, the film having a surface adapted to erasably receive writing thereon.

5. The writing board of claim 4, wherein the film is a polyester, a UV cured polyurethane, or a polypropylene.

6. The writing board of claim 1, wherein the at least one holding mechanism comprises a resilient member, at least one cable connected to at least one end of the resilient member, and at least one anchor connected to the at least one cable and to the at least one outer panel.

7. The writing board of claim 6, wherein the at least one holding mechanism is housed in at least one trim panel removably affixed to a peripheral edge of the substrate.

8. The writing board of claim 6, wherein a portion of the at least one holding mechanism is housed in at least one flute formed between two adjacent ribs, the front panel, and the rear panel of the substrate.

9. The writing board of claim 8, wherein the at least one holding mechanism further comprises at least one hinge comprising a plurality of flute mounts, wherein the flute mounts are mounted inside the at least one flute on respective sides of the at least one backslit to secure the at least one hinge to the substrate and to permit articulation of the at least one outer panel.

10. The writing board of claim 1, wherein the at least one holding mechanism exerts a force to the at least one outer panel that varies during articulation of the at least one outer panel.

11. The writing board of claim 10, wherein the force increases from a first minimum when the at least one outer panel is in the substantially open, unfolded position to a maximum when the at least one outer panel is in a partially articulated position, then decreases to a second minimum when the at least one outer panel is in the substantially closed, folded position, each of the at least one holding mechanism being in tension when the at least one outer panel is in the substantially open, unfolded position and in the substantially closed, folded position to create a tendency for maintaining the outer panel in the substantially open, unfolded position and the substantially closed, folded position.

12. The writing board of claim 1, further including a writing instrument holder affixed to the substrate, comprising

an eraser mount for detachably receiving an eraser, and

at least one clip for detachably receiving at least one writing instrument,

wherein the at least one outer panel is configured to avoid interference with the writing instrument holder when the at least one outer panel is articulated to and from the substantially closed, folded position.

13. A writing board, comprising:

a substrate comprising a front panel and a rear panel separated by a spacer, wherein the front panel and the rear panel are integrally formed with the spacer;

at least one backslit formed in the rear panel;

at least one living hinge formed in the front panel opposite the at least one backslit to form at least one outer panel; and

at least one holding mechanism operable to maintain the outer panel in one of a substantially open, unfolded position or a substantially closed, folded position.

14. The writing board of claim 13, further including a film affixed to at least one of the front or rear panels of the substrate, the film having a surface adapted to erasably receive writing thereon.

15. The writing board of claim 13, wherein the substrate comprises one of corrugated paper, a foam, a metal, or a plastic.

16. The writing board of claim 13, wherein the spacer is formed as a solid, a porous solid, a plurality of spaced apart ribs, a plurality of honeycomb cells, or a plurality of corrugations.

17. The writing board of claim 13, wherein the at least one holding mechanism is housed in at least one trim panel removably affixed to a peripheral edge of the substrate.

18. The writing board of claim 17, wherein the at least one holding mechanism exerts a force to the at least one outer panel that increases from a first minimum when the at least one outer panel is in the substantially open, unfolded position to a maximum when the at least one outer panel is in a partially articulated position, then decreases to a second minimum when the at least one outer panel is in the substantially closed, folded position, each of the at least one holding mechanism being in tension when the at least one outer panel is in the substantially open, unfolded position and in the substantially closed, folded position to create a tendency for maintaining the outer panel in the substantially open, unfolded position and the substantially closed, folded position.

19. A writing board comprising:

a substrate having a front panel connected to a rear panel by a plurality of ribs, wherein at least one of the front or rear panels comprises a dry erase property; and

a plurality of outer panels formed in the substrate, the plurality of outer panels configured to articulate from a substantially open, unfolded position to a substantially closed position and from the substantially closed position to the substantially open, unfolded position, wherein the plurality of outer panels are maintainable in the substantially open, unfolded position or the substantially closed, folded position by a plurality of holding mechanisms coupled to the plurality of outer panels,

wherein a first end of each of the plurality of holding mechanisms is anchored to one of the plurality of outer panels, and a second end of each of the plurality of holding mechanisms is anchored to another of the plurality of outer panels, wherein each of the plurality of holding mechanisms is in tension when the at least one outer panel is in the substantially open, unfolded position and in the substantially closed, folded position to create a tendency for maintaining the outer panel in the substantially open, unfolded position and the substantially closed, folded position.

20.
