Previewing Congruence and Rigid MotionsGeometry» Unit:Congruence and Rigid Motions
Geometry
» Unit:
Congruence and Rigid Motions
Big Idea:Students learn what will be expected of them in this unit as they are encouraged to persevere in making sense of a pair of novel problems.
Congruence and CoincidenceGeometry» Unit:Congruence and Rigid Motions
Geometry
» Unit:
Congruence and Rigid Motions
Big Idea:Hands-on activities reinforce the connection between congruence and coincidence, helping students to go beyond "same shape, same size".
Re-Discovering SymmetryGeometry» Unit:Congruence and Rigid Motions
Geometry
» Unit:
Congruence and Rigid Motions
Big Idea:Students describe symmetry in the art of M. C. Escher and others. In the process, they learn to describe transformations that bring corresponding parts of a figure together.
Perfect PolygonsGeometry» Unit:Congruence and Rigid Motions
Geometry
» Unit:
Congruence and Rigid Motions
Big Idea:Constructing polygons inscribed in a circle allows students to experience first-hand the many congruences of a regular polygon. Besides, its fun!
Bisector BonanzaGeometry» Unit:Congruence and Rigid Motions
Geometry
» Unit:
Congruence and Rigid Motions
Big Idea:Students use compass and straight-edge, aided by tracing paper and paper-folding, to explore the properties of bisectors, while gaining insights into the workings of transformations.
The Shortest SegmentGeometry» Unit:Congruence and Rigid Motions
Geometry
» Unit:
Congruence and Rigid Motions
Big Idea:Students use the symmetry of a geometric model to reason that the shortest distance between a point and a line is a... bisector.
From Perpendiculars to ParallelsGeometry» Unit:Congruence and Rigid Motions
Geometry
» Unit:
Congruence and Rigid Motions
Big Idea:Students consolidate and extend their knowledge of constructions related to bisectors: "A perpendicular to a perpendicular is a parallel."
Reviewing CongruenceGeometry» Unit:Congruence and Rigid Motions
Geometry
» Unit:
Congruence and Rigid Motions
Big Idea:Students review homework and assess their progress. How much have we learned?
Re-Examining ReflectionsGeometry» Unit:Congruence and Rigid Motions
Geometry
» Unit:
Congruence and Rigid Motions
Big Idea:Students learn the properties of reflections by constructing one. They use these properties to solve problems involving the Gateway Arch in St. Louis.
Reconsidering RotationsGeometry» Unit:Congruence and Rigid Motions
Geometry
» Unit:
Congruence and Rigid Motions
Big Idea:Students learn how rotations work by constructing one--then use their insights to deduce the location of a missing Mars rover.
Taking Apart TranslationsGeometry» Unit:Congruence and Rigid Motions
Geometry
» Unit:
Congruence and Rigid Motions
Big Idea:Using geometric constructions and measurement to learn the properties of rigid motion via translation.
Visualizing TransformationsGeometry» Unit:Congruence and Rigid Motions
Geometry
» Unit:
Congruence and Rigid Motions
Big Idea:Students learn that knowledge--along with practice--makes perfect when it comes to predicting the result of a reflection, rotation, or translation.
Reasoning About Rigid MotionsGeometry» Unit:Congruence and Rigid Motions
Geometry
» Unit:
Congruence and Rigid Motions
Big Idea:Students learn how to use reason as well as experience to understand the result of transforming a figure. Deductive and inductive logic work hand-in-hand!
Analyzing the Symmetry of a PolygonGeometry» Unit:Congruence and Rigid Motions
Geometry
» Unit:
Congruence and Rigid Motions
Big Idea:Students use the symmetry of a polygon to deduce its properties while continuing to develop their ability to use transformations. Now, just where does that line of symmetry have to be?
Reviewing Rigid MotionsGeometry» Unit:Congruence and Rigid Motions
Geometry
» Unit:
Congruence and Rigid Motions
Big Idea:Guided notes bring what students learned about using rigid motions and congruence together as they prepare for the unit summative assessment.
Rigid Motion and Congruence Unit QuizGeometry» Unit:Congruence and Rigid Motions
Geometry
» Unit:
Congruence and Rigid Motions
Big Idea:Students complete the summative assessment for the unit. Game Day!
Describing Precise TransformationsGeometry» Unit:Congruence and Rigid Motions
Geometry
» Unit:
Congruence and Rigid Motions
Big Idea:Using dynamic geometry software, students learn to determine the precise vector, line of reflection, or center and angle of rotation that will bring parts of a triangle together.
