Reflection: Discourse and Questioning Solving Percent Problems - Section 2: Mini Lesson

 

My students had difficulty determining whether the number given in a problem was the part or the total.  For example, in the question "What is 40% of 50?" my students weren't sure what the 50 represented.  I explained the reasoning in various ways of why 50 is the total, but I could see that some students still weren't understanding it completely.

Then, I had several students share their understanding of the concept, in their own words.  I could see that it was useful for students to hear similar reasoning, but different ways of explaining it.  

As a teacher, it was an important reminder that students make great teachers.  Students often have creative and relatable ways of explaining concepts.
