Create an animation of an odometer

User clicks on each “thing” in the picture. A mark appears, indicating it’s been counted.

An animated odometer responds, the right-most digit goes up by one.

Note: The transition from 9 to 0 requires a special explanation. Perhaps: Link to the Digi Counter. Perhaps: Make the digits of the odometer multicolored – corresponding to multi-colored Digis.

Challenge: Before clicking on a bunch of things, PREDICT the position of the odometer. Then run the animation and compare.

Animation can be run faster, e.g., to see that clicking on ten things increases the tens’ digit by one.

This teaches the Counting View.
