We took these photographs especially for my webpages of Lina (the daughter of a person I work with) building a family of Sierpinski Tetrahedra . Lina likes to build all all kinds of things. Here, her dad is helping her print triangular grid paper that will greatly simply the process of this building project. A much larger set of pictures with instructions provided in visual and written form can be found on my Build Your Own Structures page. These coloring sheets are merely another way to utilize the pictures, and Lina wanted some coloring pages of her pictures. To color drawing, click to enlarge, then print on "Portrait" setting, found under "Page Setup" or "Print Options."

 
 
 

Lina's mom, Li, is watching her outline triangles on the triangular grid paper in preparation for making the tetrahedrons. Print "Portrait".

 
 
 

This is a close-up of Lina outlining equilateral triangles on the triangular grid paper. This paper can be found on Cynthia Lanius' web site out of Rice University in Houston, Texas. There is a link to Cynthia's site and the triangular grid paper on my Build Your Own Structures page. Print "Portrait."

 
 
 

Lina is folding the triangular grid paper to the outside first, because it gives her straight lines to fold on. Print "Portrait".

 
 
 

Now the solid side of the paper is folded to be on the outside. This is how the tetrahedron should be taped up. Print "Portrait".
