My opinion doesn’t really matter but I would skip the lake unless you plan on swimming too..
I would rather take my 8yr old to a pond or small lake and hunt perch.. like I said my opinion?! I speak from experience when I took my boys with me to lake but all Kiddos are different.. regardless have fun and good luck!
Sandbass are shallow most mornings with some crappie mixed in. Cut shad is doing really good right now as bait of choice early so bring your throw net.. you would need to look for a wind blown point with hard clay bottom.. cast into wind.. I usually use 1/2-3/4oz weight, double hooks with cut shad or minnows (cut) and slowly reel back to you on bottom.
If you cannot get bait .. same set up with tandem jigs will sometimes work
