Team Generator Kids Soccer - no back to back play

For the 'break rule' to actually work, that would mean that there would be two groups of 6 players alternating, with the 6 players from each group being split into two different teams each time they play. Here are the possible ways to split 12 players into 2 groups of 6, and the 6 players into two teams without duplicates:

Team A < - - > Team B xxxxxx Team C < - - > Team D
1 2 3 < - - > 4 5 6 xxxxxx 7 8 9 < - - > 10 11 12
1 2 4 < - - > 3 5 6 xxxxxx 7 8 10 < - - > 9 11 12
1 2 5 < - - > 3 4 6 xxxxxx 7 8 11 < - - > 9 10 12
1 2 6 < - - > 3 4 5 xxxxxx 7 8 12 < - - > 9 10 11
1 3 4 < - - > 2 5 6 xxxxxx 7 9 10 < - - > 8 11 12
1 3 5 < - - > 2 4 6 xxxxxx 7 9 11 < - - > 8 10 12
1 3 6 < - - > 2 4 5 xxxxxx 7 9 12 < - - > 8 10 11
1 4 5 < - - > 2 3 6 xxxxxx 7 10 11 < - - > 8 9 12
1 4 6 < - - > 2 3 5 xxxxxx 7 10 12 < - - > 8 9 11
1 5 6 < - - > 2 3 4 xxxxxx 7 11 12 < - - > 8 9 10


An easier system is to randomly split the players into two groups (a bag with 6 red and 6 blue rocks that they choose blindly from) and then each time randomly create the teams (the bag with 3 red and 3 blue rocks).

Or, if you have space, get an assistant coach and randomly split the 12 into 4 teams (a bag with 3 red, 3 blue, 3 green, and 3 yellow rocks) and play both games at the same time, then take a break. The break can be shorter than the games, so your players will have more total playing time that the alternating version that you propose. That was the system that we used when my kids were just starting - by the end of the season, they were far more advanced compared to the teams that sat half the players or played larger sided games: more time, more touches, and stress passing and triangles.
