A) The purpose of revoicing is for a student to repeat the exact words that another student has said.

B) Tossing the ball adds the interactive element to the revoicing. It also keeps their senses stimulated and helps students to work off some energy.

C) The purpose of restating is for a student to repeat what another student has said but in their own words. This shows that repetion is not always the answer and students must be able to speak the words that come naturally to them instead of sounding like a recording. Applying your own resasoning  means that you are able disagree with what someone has said. It is to show there is no one answer to everything and you must be able to defend your answers when their is somewhere there whp does not agree with you.

Talk moves where develop ways to communicate

Revoicing is a student repeat exactly what another students says

Toss a ball adds the element of interaction, some students need to move and it students keeps senses stimiulate

Restating and applying personal reasoning is where students says what someone else said in own words, and agree or disagree with what someone else says and it give chance to speak and starts communication with each other.

I like the way the teacher uses the ball to pass it along amongst the students to have them interact and listen to their peers next to repeat what the peers say along with voicing their own opinion. It helps them develop communication skills along with how to voice what your thinking. A great activity for developing language use because the students have a chance to reflect and model ways to express themselves in a language they are learning with academic terms. 

I really like the idea of "Talk Moves" and how doing class exercises like these help to keep the students engaged in learning while also working to develop their communication skills. I think this exercise in particular was really useful because of the different levels of communication the teacher incorporated: revoicing, restating, and applying reasoning. I think guiding students through each of these levels of communication helps students to reinforce their abilities and build so that they can become more effective communicators. I also really enjoyed that this activity was being used to empower English learning students, and could provide them with a strategy to better prepare them for learning in an English speaking setting.

A strategy using a ball to stimulate the brain to think and communicate.  By throwing the ball it gives each of  the students the chance  to revoice, restate and apply your own reasoning.  It helps ELL learners to develop communication skills.  It is a strategy that could be use at the learners level and motivates the students to use their words in the classroom.
