Exploring Transformations
8th grade
Description
Explore properties of transformations with the purpose of noticing patterns, making generalizations, and developing rules.

Project (or provide copies) of the Hook Overhead Sheet (PDF).
To stimulate curiosity and increase student motivation, lead the class in a brief visible thinking routine called "I see, I think, I wonder". This type of experience sets the stage for inquiry-based learning. Encouraging students to be creative and thoughtful with their observations and interpretations helps promote discourse in the classroom. (More research and graphic organizers for this routine can be found online).
Allow students 3-5 minutes to write their response prior to sharing in class.
This can be done in a variety of ways. For example:
- journals
- notebooks
- sticky notes to post on chart paper
- etc..
When sharing begins, encourage students to state all three of their responses at the same time, i.e. “I see… I think… I wonder…”
Lessons
Lesson 1 of 4
Develop an understanding of translations in the coordinate plane and determine general rules for translations through exploration.
Lesson 2 of 4
Develop an understanding of reflections in the coordinate plane, and determine general rules for reflections through exploration.
Lesson 3 of 4
Explore rotations on a coordinate plane where (0,0) is the center; determine general rules for rotations.
Lesson 4 of 4
Students will develop an understanding of dilations on the coordinate plane and general rules for dilating an image through exploration.
