Lesson by Melissa Miller
What Shape Is That?
(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.
