I have a Canon 5D with 28-105 lens I have been using and am struggling to capture pictures of 6 kids together and everyone being in focus. Any suggestions on what I could be doing wrong?

Generally, If you focus on a given point, DOF extends from 30% from that point towards you to 70% away from that point at "normal" distances. For close-ups, it's more like 50% & 50%.
DOF depends on the distance AND focal length of the lens AND the f-stop. So there isn't any "rule of thumb setting" until you standardize two of the variables?
