HELP!!!

Ok, I need some help! Argh! We are *almost* done with school (Ashton, specifically). We're finishing up history and language, and just plan to keep on with math over the summer in a more relaxed pace. Right now, however, while finishing up, we're kinda "cramming" for testing, which is on the 15th and 16th. I'm feeling pretty good about what we've accomplished. BUT....the boys are driving me nuts!

Apparently, watching videos, playing on the computer and on XBox, making "playgrounds" for the turtles, playing in the sandbox and swimming pool, chasing the dogs, digging in the dirt to make tracks for cars, and digging for rocks just isn't enough activity. Apparently, we need some more stuff to do. Go figure. So, while I'm working diligently with Ashton, they're fighting and throwing things at each other and taking each other's toys and basically doing anything they can to annoy the other one or destroy the house and yard. I know. I know that they need some "organized" activities, but what kind? I'm so used to girls that I could say, "Hey, let's play with some playdough!" or "Let's paint!". These activities just don't end up the same with boys. And, I for sure, can't leave them to do these on their own. So, what can I give them to do that will keep them busy while I'm trying desperately to finish up Ashton's school? Some of you guys have boys, so can you please give me some ideas of stuff I can do with the boys to keep them busy and entertained??
Thanks.

In other news....
Yeah! I worked out this morning! Whoo hoo! I'm so proud!

Oh, and we lost a turtle yesterday. It was the box turtle that someone saved from an untimely death on I-95 about 4 years ago, and gave to us. We named him "Speedo" for a reason. He's fast! So, yesterday, Indy took some of the little turtles out to play with and apparently Speedo got away, but Indy neglected to tell me. He told his dad about 7:30 last night, so we were outside, in the dark, looking for a fast turtle who had a, what, 8 hour head start? Yeah, right. Of course, we didn't find him. I was relieved it was the "free" turtle instead of one we actually paid for, but Nicky wasn't so happy. :-(

Ok, I guess that's it for now. LMK if you have any ideas to help me with the boys....
