          Lesson by Melissa Miller
          What Shape Is That?
                        First Grade TEKS
(1.6) Geometry and spatial reasoning. The student uses attributes to
   identify two- and three-dimensional geometric figures. The student
   compares and contrasts two- and three-dimensional geometric figures or
   both. The student is expected to:
             (A) describe and identify two-dimensional geometric figures,
               including circles, triangles, rectangles, and squares (a special
               type of rectangle);
             (B) describe and identify three-dimensional geometric figures,
               including spheres, rectangular prisms (including cubes),
               cylinders, and cones; and
             (D) use concrete models to combine two-dimensional geometric
               figures to make new geometric figures.
