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:
- 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?
