The Full Pattern
Sixteen rows complete the next step of the Sierpinski pattern. Once colored, the odd cells show the same triangle at several sizes, a clear first look at a fractal.
Small Blanks in a Big Triangle
The triangle contains numbers in the thousands, but the blanks stay at two digits, so the sheet is about patience and pattern rather than heavy calculation. The parity of the large numbers can still be read from those printed.
Smaller Cells, Finer Work
With 136 cells on one page, each hexagon is smaller than on the other sizes. Fine markers or colored pencils work best for the coloring.
