## Reflection: Flexibility Dig In! Day 1 - Section 1: Think Geometry

The creation of this list was a last minute idea and it was key!  When I asked the students later in the lesson to categorize their figures, the students referred to their list of geometric concepts totally on their own - no hints from me!  As a result, the scope of their categories was much larger and much more interesting than I had previously seen for this lesson, and the students required fewer hints from me when they were considering their options.

The list included polygons, triangles, parallel and perpendicular lines, area and perimeter, volume and surface area, the Pythagorean Theorem, trigonometry, transformations, symmetry, types of angles...
