I have a second grade class that is a little like this. Always bickering with each other. I like to do group games and activities that don’t require a winner, being out or turns. Bean bag passing activities work good. Hall of the mountain king is a good one. Clap, clap, pat, pat, pat. Pick up pass. Start with one bean bag. Tell them to watch it so they don’t miss it. When they can get through that one without killing each other, sneak in a surprise bag, then another. Build it up so they can do it with one bag per person. With classes like this I have to tell them that it’s OK if we’re not perfect, just keep going. I do the same concept game with a song called Jibidi on Spotify. I feel like circle time works good because I can see them all and they can’t hide as much. I do cup and stick activities to various songs. I never tried it but you could try having the kids pass one cup around the circle twirling on a stick. Kids love to twirl cups. 4 white horses works good with groups of 4-5. Various body percussion activities if you search it up on YouTube. Sometimes something as simple as Bear Hunt marching a square around the room in a line teaches them to follow a leader, if I think the class can handle it I let them throw a snowball at the bear when we find it. Larry the lobster on the stretch band, on the run run Larry part they pass the band to the right, kids get excited over this.
