Learning Experience/Unit

Flipped Out! by St. Lawrence-Lewis BOCES

Course, Subject

Geometry (Next Generation), Math, Science & Technology, Mathematics (NYS P-12 Next Generation)

Grade Levels

Intermediate, 8th Grade

Assessment

This learning experience will be assessed using a rubric that evaluates the students' ability to illustrate the topic of their choice (line symmetry, point symmetry, line reflection, point reflection) and how or where their topic is used in everyday life or the real world. They will express these ideas through a PowerPoint presentation.

Learning Context/ Introduction

Students will learn about reflections, rotations, and symmetries.
Students will reflect lines, points, and figures about axes, lines, and points.
Students will rotate figures about points.
Students will identify line, point, and rotational symmetries as well as symmetries found in their everyday lives.
Students will create a Microsoft PowerPoint about one of the topics aforementioned to show what they have learned or understand .

Duration

Four Days Total (42 Minute Periods):
Two- Instructional Days
Two-Lab Days

Essential Question

Where are transformations and symmetries used or seen in the real world?

Instructional/Environment Modifications

Instructional: Students with special needs will be given an appropriate amount of extra time.
Students that are gifted will be challenged to work on the more advanced functions of PowerPoint.

Environmental: Computer, LCD projector, SMART Technologies Airliner

Procedure

Day 1: Reflections

A. Line Reflections

1. Teacher will introduce line reflections. Specifically these two special cases: x-axis and y-axis. The rule for a reflection is the x-axis is P(x,y)-->P'(x,-y) and the rule for a reflection in the y-axis is P(x,y)-->P'(-x,y).

B. Point Reflections

1. Teacher will introduce point reflections. Specifically a reflection in the origin will be discussed. The rule for a reflection in the origin is P(x,y)-->P'(-x,-y).

Day 2: Symmetry

A. Line Symmetry

1. Teacher will introduce the basics of line symmetry using the shapes from the SMART Technologies Airliner software and drawing lines through them using the SMART Technologies Airliner software.[See attached files for examples.]

B. Point Symmetry

1. Teacher will introduce the basics of point symmetry using the shapes from the SMART Technologies Airliner software and flipping them upside down to see if they look exactly the same. [See attached files for examples.]

C. Rotational Symmetry

1. Teacher will introduce the basics of rotational symmetry using the shapes from the SMART Technologies Airliner software and rotating them using the SMART Technologies Airliner software to see if they look exactly the same after being rotated. [See attached files for examples.]

D. Real World Examples

1. Teacher will use the attached SMART Technologies Airliner slide to exemplify real world examples of symmetry. [See attached files for examples.]

E. Sample Project

1. Teacher will present a sample PowerPoint project for the students. The students will also be given and explained the criteria of the rubric.

2. The students will decide which topic they want to do their project on. They will also create an outline for their PP presentation.

Day 3: Project Review

A. The students and teacher will meet to review the student's outlines.

The outline will include a title for the presentation, the content needed to explain the topic they chose, and how their topic relates to the real world.

Day 4: Project Construction (Computer Lab)

A. The students will work on constructing their PowerPoint projects.

1. Students will create a title page.
2. Students will create instructional pages for their topics.
3. Students will create a page(s) exemplifying their symmetry topic in real world examples.

B. The teacher will circulate to help students create their projects.
