Multiplication is…

yea, I know, it’s not “just repeated addition.”

In fact, I’m having a separate short Camtasia for repeated addition, arrays, and rates.

However, I found this gem of a lesson from https://www.illustrativemathematics.org/content-standards/tasks/365  taht includes this:

  1. Mel is designing cards. She has 4 different colors of paper and 7 different pictures she can glue on the paper. How many different card designs can she make using one color of paper and one picture?

Which category would that fit into — or does it need one of its own?
