Reflection: Adjustments to Practice Markdown Percent Models - What Percent Are You Paying? - Section 2: Explore


I did not get to the gallery walk in all of my classes.  It took about 3/4 of the class to get through the opener and notes.  Kids understood the concept, I think I just had to many practice problems before the gallery walk.  I like to give groups time to work together and then put work on the board, so this took time.  In two of my blocks I was able to do start the gallery walk, and kids were able to finish about half of it.

The biggest struggle that my students had with the gallery walk was distinguishing whether a problem was asking for a discount or just percent of a number.  My lower readers that just like to pull numbers from problems struggled the most - as they did not look for key phrases or terms such as coupon, discount, mark down.  I think the activity was worth it for those that got the opportunity to do it, however, as it did require them to stop and think about what the problem was asking - it was not just a regurgitation of what we did in today's lesson, it covered the previous lesson as well.

I am super pleased, however, with how the conceptual bar model approach is going, and I like that kids are able to see that if something is 20% off, that they are paying 80% of it - that will help ease the calculations when I actually let them use a calculator!
