Elapsed Time Backwards N Strategy. Here is a file that contains 5 pictures that Melissa, from The OC Blog Facebook Fan Page, sent to me to post for everyone to see. It is a strategy used to teach elapsed time. Thanks Melissa!
Another pinner said: I add each cat chased 8 mice (ounces). I know it doesn't start with O, but they are small and so are ounces.
