Use 7-day 4-doses-a-day pill-organizers to introduce students to 2D arrays because these create an interactive, 7-by-4 two-dimensional array that helps students visualize this abstract concept.

Misconception: Students may think that assigning one array to point to another array makes a copy of that array, failing to make a distinction between shallow and deep copies.
