Types of transformations addressed are: translations, rotations, reflections, and dilations.Figures are referred to using both vertex names and cartesian coordinates.
The objectives of this lesson are to help students identify images and preimages of a mapping and recognize an isometry.
This lesson could also be taught as a presentation with the whole class working together.
The objective of the second lesson is to name a reflection image, to recognize line and point symmetry, and to draw a reflection image.
The objective of this lesson is to name a translation image with respect to parallel lines and to draw a such a translation image.
The objective of this lesson is to help students name a rotation image with respect to intersecting lines and to draw a such a rotation image.
The objective of this lesson is to help students understand the meaning of scale factors, identify the center and scale factor of a dilation, and draw a dilation given a center and scale factors.
Review the content periodically as misunderstandings become apparent. Spend time after all the lessons are completed to review properties of each transformation and how each transformation is constructed before having students complete the quiz.
Ask students to complete the online Quiz. If they have time, ask them to complete the Student Feedback Questionaire as well.
Geometry - Standard 3. Apply transformations and use symmetry to analyze mathematical situations.
Strand 4. Concept 2. Apply spatial reasoning to create transformations and use symmetry to analyze mathematical situations.
