Are Calendar Math and morning meeting different? I want to do calendar math this year, but really can't think in more complex terms...I am stuck on the simple addition, subtraction, and patterns that are done in the early grades. I definitely plan on working the phases of the moon into it, but would love some good examples of calendar math at the third grade level. I have never done this at all, so if you are even willing to type up an entire calendar math session that you may have, it would help me in knowing where to start, what to say, etc... Thanks!!
