## Reflection: Developing a Conceptual Understanding Putting it Together: Working with Plane Shapes - Section 4: Independent Practice and Informal Assessment

This lesson might appear "basic", especially to someone who is not familiar with kindergarteners.  One assessment we administer to kindergarteners in our school is House, Tree, Me.  For this assessment, the students must draw a picture of a tree, a house and of themselves.  The students are scored based on the accuracy of their drawings (Can you tell it is a tree?) and the number of details (Is there a body?  Are there fingers, etc?).   The pictures show a student's level of sophistication in representing real world objects.

This math lesson helps develop the specific skills scored by this assessment.  Students learn that a house is a square with a triangle.  They learn that additional details like windows can be added to the drawing simply by drawing some rectangles.  Their drawings begin to develop the sophistication that we look for as kindergarten draws to a close.

As teachers, we can have a formative role in this development beyond a math lesson on shapes.  It is critical that we model drawing for our students and talk them through the process.  We need to say things like, "I want to make a wagon.  I know the bottom of the wagon is shaped like a rectangle. The wheels are circles.  The handle is another rectangle, but this time it is a skinny one."  This modeling refines communication and drawing skills, and also helps those students who have difficulty breaking down tasks into discrete steps.
