## Reflection: Grappling with Complexity Assessing Composing and Decomposing Shapes - Section 2: Assessment: Making Hexagon Shapes

Please watch the video link My Reflection on the Assessment as it will inform you what I was looking for with the assessment piece. For an example of a child who clearly understands how to use two shapes to create another shape, please watch the link Student Explanation of Thinking.  There is also a sample of student work (of the assessment) in the resource section.
