• Resumen

  • Permutations and combinations are standard components of the secondary math curriculum (CCSSI 2010, HSS.CP.B.9; NCTM 2000). In my classes, I have used counting problems to help students look for and make use of structure, as well as to model with mathematics�two important standards of mathematical practice (CCSSI 2010, MP.4, MP.7). Furthermore, I have found that combinatorics problems can motivate problem solving, because it is not always clear what the outcome of such problems should be.
