Activities with pit bull puppy?

She's 8 weeks old (put 10 on other question by accident). I named her Brownie. (She stole my friggin brownie). She's a good girl. So Sunday, it's playtime. What should I do with her. She likes to run around so I figured play outside, if it don't rain. She's playing with her rope right now. We have her sister and a different pit pup, all within 4 weeks of each other. Brownie is mine, Blue was mine, but is now my sisters, and Pebbles is my brothers.
