A number is called fortuitous if it is equal to the product of the lengths of the words in its spelledout name. E.g., ‘twentyfour’ is 6 x 4 = 24, or ‘eighty four thousand six hundred seventy two’ is 6 x 4 x 8 x 3 x 7 x 7 x 3 = 84,672. (h/t @_FutilityCloset)

Teacher, do your students have access to computers such as tablets, iPads or Laptops?
