## Reflection: Flexibility Estimating & Measuring Weight - Section 3: Student Practice

I wasn't expecting a student to find large discrepancies between the labeled weight of a product and the digit scale reading. In this video, Imperfect Digital Scales, a student shows me the contradicting data. This goes to show how important flexibility is, even when you think you've planned a great lesson! I also watched another student use a digital scale to weigh a product before estimating, which as you can imagine, frustrated his group members. Next time I teach this lesson, I'll be sure to provide more guidelines on the use of the digital scales. At the same time, I will be ready for unplanned moments to happen!
