Reflection: Developing a Conceptual Understanding 2D Shapes on 3D Shapes - Section 1: Activating Strategy


By starting this lesson in allowing the students to press 3D shapes into play-doh, it really allowed them to conceptualize the various 2D shapes that are on 3D shapes.  This proved to be a great activating strategy, and one that helped them to understand the concept of the standard and successfully master it.  By allowing them to press the 3D shapes into play-doh, it also helped them to use tools to solve math problems (MP5)
