When I coached this age I, I put the kids in alphabetical order for their batting lineup. The next game the last batter would rotate to lead off, and everyone else would move down a slot.
For fielding I put them in the same order by position number 1-9 and then moved them up a position midway through each game and then the next game. Pitcher would go to catcher, right field would come to pitcher, etc. This generally worked pretty good, but you always had to improvise when players weren't there. Also had to watch pitcher and 1st base as mentioned to not get a kid hit by not paying attention.
I helped coach my son's 8u team last year and 9u this year. We use this sheet, nothing too sophisticated, but helps keep track of positions and obviously not set in stone because things can happen thought the game. We use the Gamechanger app also. Pretty cool. Keeps track of stats and pitches, when you get to that level. Our lineup is just a random draw, or we just flip it from game to game for league. Tournaments is different lineup wise. Whoever said 2-3 coaches is correct! We have 3 and it's a handful even with 9u at times.
