## Reflection: Intrinsic Motivation Price Comparisons - Section 2: The Biggest Bargain

Asking students to find the best prices proved to be very motivating. Students seemed excited to be finding the best deal and worked hard to figure things out. Students may have seen their parents shopping for the best deal, or they may realize if they don't buy the most expensive of something when they have birthday money, etc., they may be able to get something extra.

Either way, this was a real life problem that students found to be very motivating. For me it was helpful to view the strategies that students employed to find the differences between the two prices. I saw students using expanded form, columns, and still number grids to solve their problems. It is my goal by the end of the year to help students move from the number grid as their only tool to other forms that may be more easily accessible in third grade. I want students to begin to internalize the strategies that we have introduced in second grade and know when they can draw from one strategy or another to help them model with mathematics in a way that makes sense to them (MP4).
