Depends on the maturity of the kids, but I like to group sections together at this point during sectionals.

I have trumpets/clarinets/flutes come in together and then divide into small trios or more as needed. I have a leader in each group and they work on matching articulation and intonation. Gives them a little more control and responsibility and they enjoy that I'm not hammering them.

It really helps open their ears and it helps develop more ownership of their own success. They also don't like to be the weakest in the group.

I typically have upper winds, low winds, and middle winds. Also helps to cut down the number of sectionals as I'm starting to get worn down.
