Atticus found out about the children's game involving Boo Radley when Heck Tate mentioned it during Tom Robinson's trial.

I think that Jem confessed to Atticus about the children's wrong doing because when he found the blanket around Scout's shoulders it instantly hit him that it was Atticus. I feel that Jem thought that Atticus was going to complain to Mr. Radley aobut Boo. Jem felt scared for Boo because he didn't want Boo getting hurt. Jem then started blurting out confeessions about how Boo was innocent. how boo could have but didn't hurt them. Jem confessed because in the end he wanted to thank Boo for all he did for them.
