Reflection: Diverse Entry Points Reflectional and Rotational Symmetry - Section 1: Do Now


When I planned this Do Now, I left the choices for types of symmetry open. This allowed me to assess the students' prior knowledge on the subject. Many of the students recognized the letters as having line symmetry (reflectional symmetry), but few recognized the letters as having point symmetry (rotational symmetry). They also had some difficulty verbalizing their descriptions of the type of symmetry, i.e. vertical line or horizontal line symmetry. The activity did allow for student choice and gave the students the opportunity to create their own category and share their ideas with other students when we went over the activity. 

For some of the students who were having difficulty, I used the "Scaffolded Do Now." On that page, they were given the types of symmetries and had to identify the letters that fit the category.

Reflectional and Rotational Symmetry

Unit 3: Transformational Geometry
Lesson 1 of 10

Objective: SWBAT Identify objects with reflectional and rotational symmetry.

Big Idea: This is the first lesson in a unit on transformations. Students will examine different objects and identify their symmetries and orders of rotation based on their prior knowledge from the eighth grade.
