Geometry:
The student demonstrates conceptual understanding of similarity, congruence, symmetry, or transformations of shapes.
 Calculating...
Lesson  (...)
Lesson: Students consider the patterns that emerge from agent models and geometric fractals.

Lesson: Explores lines, planes, angles, and polygons in tessellations.

Lesson: Students learn to identify a variety of patterns using sequences and tessellations.

Lesson: Examines plane symmetry.

Lesson: This lesson shows elementary students how they can know, for certain, that rigid motions like reflections, rotations, and translations create a shape congruent to the original.

Lesson: Introduces students to concepts of transformations.

Lesson: Explore the mathematical nature of art and tilings and looks at the role of math in nature and our culture.

Activity  (...)
Activity: Build your own polygon and transform it in the Cartesian coordinate system. Experiment with reflections across any line, revolving around any line (which yields a 3-D image), rotations about any point, and translations in any direction.

Activity: Build a "floor tile" by dragging the corners of a quadrilateral. Learn about tessellation of quadrilateral figures when the shape you built is tiled over an area.

Activity: Create a tessellation by deforming a triangle, rectangle or hexagon to form a polygon that tiles the plane. Corners of the polygons may be dragged, and corresponding edges of the polygons may be dragged. Parameters: Colors, starting polygon.

Activity: Explore the world of translations, reflections, and rotations in the Cartesian coordinate system by transforming squares, triangles and parallelograms. Parameters: Shape, x or y translation, x or y reflection, angle of rotation.

Activity: Build your own polygon and transform it in the Cartesian coordinate system. Experiment with reflections across any line, rotations about any point, and translations in any direction. Parameters: Shape, x or y translation, x or y reflection, angle of rotation
