Instead of a still or drawing I took my classes out into the teacher parking lot and we walk around from car to car picking on the uglier cars, and not accidentally, skipping my car altogether…that s until one of the students managed to find it.

We also did this with phone numbers, area codes, exchanges, gmail passwords, etc.

I also would have used Nat’s idea above but made it a broader number sense/algebra game for kids to take with them everywhere: each time you pull up behind a plate at an intersection, formulate a number sentence by adding symbols anywhere amid the letters and numbers on that plate to create a true statement:

6+95-2=99 That one was too easy.
