This would be a climb right up the center of the face starting from the small boulder. This isn't the easiest climbing, I would say it's in the 5.6+ range, it isn't hard just a little thin at the bottom.
Because of the reason I'm posting this route I'm going to list the protection as saying you should build anchors at the top and top rope it as that will make the person climbing feel safe. I have some 1/4 ropes which would be fine for this. Use caution, common sense and if you don't know how to build anchors have somebody teach you.
With all that said this would be a good spot for 4-10 year olds.
