## Reflection: Grappling with Complexity Two-Step Word Problems (Result Unknown) - Section 2: Introduction to New Material

During this lesson, I allow students to set up their number sentences in a way that makes sense to them.  This practice allows students to grapple with the problem at home and develop a conceptual understanding.  When students struggle to build their own number sentences, I encourage them to draw a picture.  Drawing a picture allows them to visualize the "action" in the problem which then allows them to build a number sentence that makes sense to them.  I find that encouraging students to draw pictures and then to build their own number sentences allows students to really read the problem, visualize it, and then solve it accordingly.  Because of this practice, I find that my students are less likely to fall into common pitfalls like using the wrong operation for a problem.
