## Reflection: Perseverance More Practice with Percents - Practice Makes Perfect! - Section 2: Explore

My students thoroughly enjoyed today's game.  I find that my two group reviews really bring out the mathematical conversation and reasoning between students.

In this particular case, I had a question regarding a markup.  The students were given the marked up price, the mark up percent, and were asked for the cost to the store.  I couldn't get my phone out in time to video the discussion, but it was awesome!  Only one or two students in each group understood that they were looking for the original price - they struggle to wrap their brains around the concept of marking something up (not tax and tip, but rather marking up for profit).  I had one student in my 4th block really go around and help her group - and in defending her answer she talked said "if we do it your way the store doesn't make any money, they lose money, so that doesn't make sense."  I LOVE when kids realize the reasonableness of an answer.  This type of question also made connections to the real world - which is key for student understanding.  As soon as Elizabeth said - "the store won't make money your way," kids started listening to what she had to say.
