4.9  The student connects transformations to congruence and symmetry.
PK	K	1	2	3	4	5
-Slide, flip , and turn shapes to demonstrate that shapes remain the same. -Begin to investigate the results of putting 2 or more shapes together	K Investigate and predict the results of putting 2 or more shapes together	1.6 d  Use concrete models to combine 2D geometric figures to make new geometric figures	2.7c  cut 2D geometric figures apart and identify the new geometric figures formed	3.9a  Identify congruent 2-dimensional figures. 3.9b  Create 2D figures with lines of symmetry using concrete models and technology 3.9c   Identify lines of symmetry in 2D geometric figures	4.9b  Use translations, reflections, and rotations to verify that two shapes are congruent	5.8a  Sketch the results of translations, rotations, and reflections on a Quadrant I grid. 5.8b  Identify the transformation that gererates one figure from the other when given 2 congruent figures on a Quadrant I coordinate grid
Use translations to verify that 2 shapes are congruent Use reflections to verify that 2 shapes are congruent Use rotations to verify that 2 shapes are congruent Use:  to employ for some purpose; put into service; make use of Verify:  to ascertain the truth or correctness of, as by examination, research or comparison
