## Reflection: Developing a Conceptual Understanding Do You Know The Difference? - Section 4: Independent Thinkers!

In a multiplicative comparison, the underling question is what amount would be added to one quantity in order to result in the other. In a multiplicative comparison, the underlying question is what factor would multiply one quantity in order to result in the other. Even though, students could give the correct answer, some of them had a difficult time explaining how they got their answers.  For instance, some students gave an explanation, but they fail to communicate their thinking precisely.  To fix this I simply wrote an explanation on the board, and ask students to assist me in stating the explanation a bit more precise. Students seemed to be able to discuss their thinking better after they had time to work on explaining.  According to Common Core mathematically proficient students communicate precisely by engaging in discussion about their reasoning using appropriate mathematical language.
