This is just a small idea that I took from some other whole brain teachers. When I had my kids read in groups of four the other day I clapped and said "read" and they clapped and said "okay". This is the same idea as "teach"/"okay", but it cues them to a different activity instead.
I know that some whole brain teachers use reciprocal reading or reciprocal teaching along with teach/okay and it works nicely. You just have to explain each role ahead of time; maybe give them a handout that describes each. I believe the different roles are usually summarizing, questioning, clarifying, and predicting. You give them a set amount of the text to read and then when they are done, they do their jobs. I haven't used it much, but I plan on using more of it this year. It is nice because the kids are in a group of four and they keep each other accountable. I think giving the kids specific roles to do in their reading assignments makes them engaged and it lends itself nicely to teach/okay because they read and work in chunks instead of reading the entire passage at once.
If anyone has gestures for these roles- summarizing, questioning, clarifying, and predicting- I would love a suggestion.
