matlactetl once (Osu2v)
This notation for the number eleven (11) consists of two groups of five small circles in a horizontal row, plus one more circle above the far right end of the row. Each group of five is connected with a horizontal line along underneath the circles. The groups of five suggest the use of hands and fingers for counting. The circles are painted a light brown or tan color. The equation is 5 + 5 + 1 = 11. It comes from the Codex Osuna, folio 2 recto (Image 6).

Matlactetl is another way of saying matlactli. This number is part of a larger number that totals 171 and refers to that number of bundles of lime (a tribute item extracted for use in construction). These numbers could be taught as part of a mathematical lesson. The full number has eight flags (tecpantli), each worth 20, for a subtotal of 160. Adding the 11 brings the grand total to 171. It is just a coincidence that the “once” in this number sounds like the Spanish word for eleven. The Nahuatl word actually means “plus one,” part of a construction that is five plus five plus one.
