In the story, How to Kill a Mockingbird, the kids try and persuade Boo to come out. Does he? And how many times does he come out?
The children make numerous attempts to get a look at Boo Radley and persuade him to come out of his house. In chapter 5, Jem and Dill write Boo a polite note asking him to step outside and explain what he does inside his home all day. Jem and Dill also remember to tell Boo that they won't hurt him and will buy him ice cream if he comes out. Unfortunately, Atticus catches Jem attempting to leave the note on Boo's window sill using a fishing pole. The children also sneak into Boo's backyard and attempt to get a look at him through his window. However, they are unsuccessful and forced to flee the yard after Nathan Radley comes out of the house with a shotgun. After Jem realizes that Boo is the anonymous person leaving them gifts in the knothole of the tree, he writes a letter thanking the person for the gifts. Unfortunately, Boo does not receive the letter because Nathan fills the knothole in with cement.
Boo leaves his home and goes outside several times throughout the novel. Boo leaves his home multiple times to place Jem and Scout's gifts in the knothole of the tree in his front yard. Boo also leaves his home during Maudie's house fire to put a blanket on Scout, who is standing in his front yard. Boo also leaves his home towards the end of the novel when he intervenes during Bob Ewell's attack to protect Jem and Scout.
Right from the beginning of the book, the children, especially Dill, are fascinated and petrified of Boo. I am not sure that how badly they want to get him out. We need to keep in mind that they were scared of him.
What the children do is go by Boo's house out of curiosity. On one occasion, they get in a tire and Scout rolls into Boo's yard. On another occasion, they trespass and Jem's pants get stuck in the fence. And still another time, Jem runs up to touch the house and runs back.
Are these ways the children want to make Boo come out? It is debatable.
As to how many times Boo came out, this cannot be answered with any degree of certainty. All we know is that Boo came out. For example, he is the one who put the gifts in the tree knot. He also got Jem's pants and fixed them. He also put a blanket around Scout's shoulder while Ms. Maudie's house was burning. And finally, he was watching them when Mr. Ewell attacked.
In light of this, we can say that he came out many times.
