I'd have my students reverse engineer banknotes and license plates:
And then I'd serve them up plain …
… and ask the students to:
- determine the elements that comprised the banknote or license plate (and, in the case, of banknotes, there are usually a lot of elements — historical figures, state birds, even the color scheme matters)
- speculate on what country/state the banknote/plate belongs to.
- explain each element in the context of its country/state.
I'm just armchair quarterbacking here, though.
