Reflection: Discourse and Questioning Break Even Day 2 of 2 - Section 4: Closing the Lesson

 

Students made really good connections to solving for the break even point using number sense and I wanted to high light this number sense against those students who chose to solve the questions more algebraically using equations and isolating the variable.  Here are two student presentations from class where we discussed the similarities between both student presentations in an effort to move students toward the algebraic solving equations but with conceptual understanding.
