So...I'm new to fourth this year(taught fifth last year), and I'm considering calendar math. In teaching fifth last year, I noticed most of my students came to fifth without having mastery of fourth grade standards (long story, but math was a HUGE issue with fourth grade teachers at my school. Most of them were moved). I think calendar math would be a good way for them to reinforce those skills on a daily basis. Do any of you currently do calendar math? How much time does it take each day? I've been checking out the calendar math resources on "teaching in room 6". I thought calendar math was more for younger kids, but she has great ideas for older kids. Your thoughts?
