## Reflection: Problem-based Approaches In the Box: Rectangular Prisms and Cubes - Section 1: Opening

My M.Ed. program focused heavily on the use of constructivist practices in the classroom.  In the years since I completed my Masters, I have moved a way from constructivism.  As much as I believe in constructivism, often times the lessons can be time intensive to plan.  This lesson reminded me how important it is to incorporate lessons that are constructivist in nature.

The students were really pushed to think in this activity.  I didn't tell them what qualities their cards shared.  They had to come up with that on their own.  I heard some impressive conversations occur during this activity, showing some higher level thinking skills.  The students were also pushed to use their academic vocabulary as they were conversing.

The activity did take a little more time than some of my lesson openings, but I think it did a better job of getting my students thinking.  In a world where the answers are just a "click away", we need to teach our students that the answers are there if they search for them.
