Three on Thursday: Is it Poison Ivy?

I have three pictures for you. I wonder if you can tell me if they are poison Ivy. I found them growing in the shady area of my yard. There are some dead vines there as well. I'm starting to pull them out, just in case. Will you let me know if you can tell that they're the kind that gives rashes. My kids plays on this yard, and I just want to make sure they're not going to harm themselves hanging out there.
