I'm teacher assissting this semester in a 3rd-5th grade resource room and I'm going to be starting a unit on time. I want to ease the students into each concept of time seperately. The question I have now is rather or not I should introduce the concept of AM and PM before or after teaching the students about the hands on the clock. I thought that the AM and PM one would be the most basic one that they could get down with ease. What do you all think?
