Reflection: Discourse and Questioning To Subtract Me is to Add Me - Section 4: Solving Subtraction Equations on the White Board


In this activity, I had students check with their shoulder parnter.  The check went something like this.  Student A, please explain to student B how you solved your equation.  Then student B shares with student A.  Students are expected to speak mathematical (MP6).


When the students were done sharing with a partner, I chose students , randomly, to come up and explain how they solved the equations.  Giving the students time to explain their thinking while using mathematical language supports discourse and questioning.
