Math for English Majors

Investigations homework from Younger Daughter's backpack:

If it's hard to read, the instructions say:
Explain why the image below is or is not an array using 4 or more lines and the following words
  • Array
  • Dimension
I don't know what the right answer is here.  Is it not an array because the items are not all the same size and shape, as YD wrote?  Or is it an array because it's arranged in a 3 x 5 grid?

Meanwhile, I'm still trying to teach YD the times tables, or "Multiplication Combinations" as Investigations calls them.
