There's a guy I've seen on here somewhere that has posted a map of a lot of ponds in the DFW area including south dallas. I think it was a google map that had pins dropped. Maybe someone will remember who that is and he can hook you up of one of his maps. Maybe was in the bank fishing section.
Right now, or in about 28 days from now and a week or so both ways the big mommas and daddies will be up on their beds and if you can find the right pond could get some really nice size ones.
Live crickets are hard to beat. Long shank size 6 cricket hooks bent at around a 60 degree angle about half way down work good to keep them from swallowing it. Use a little small split shot with a small light styrofoam orange and white float and let the wind drift it can work or fish them on the bottom or a slow retieve with no float can all work well depending on conditions.
Good luck and post some pics of your daughter catching some of those monsters. They are happy with any size and if you filet them right even the little ones can sure be tasty and no bones
