Can you find the Line of Symmetry?
This lesson is about lines of symmetry. Students will learn and practice lines of symmetry on many objects in a variety of ways.

In this lesson students will practice finding a line of symmetry for 2 dimensional shapes. They will be able to fold along the line as well as draw the line of symmetry.
- Face to face, small group
- 30 Minutes
Background for Teachers
To teach this lesson, you will need an understanding of Pages on the iPad. You will also need knowledge of lines of symmetry. There are a couple of videos tha can help teach lines of symmerty!
Step 1 - Goals and Outcomes
Recognize a line of symmetry for a two-dimensional figure as a line across the figure such that the figure can be folded along the line into matching parts. Identify line-symmetric figures and draw lines of symmetry.
- Students will be able to identify lines of symmetry in 2 dimensional shapes.
- Studens will be able to use Pages on iPad to complete assignment.
Step 2 - Planning Instruction
Student Background Knowledge
Prior to this lesson, students will need to have an understanding of how to use Pages app on the iPad. They will also need to be able to work in small groups. Students should also be able to identify different shapes.
Strategies for Diverse Learners
Students will be working in small groups. Peer tutoring will be a great way to help students who may not understand.
Step 3 - Instruction
Start out as whole class teaching of lines of symmetry. Display some shapes and objects that do and do not have lines of symmetry for example; alphabet letters, square, triangle, parallelogram, scalene triangle. Share the definiton of line of symmetry with students. Have students read it aloud as well as repeat back to a shoulder partner. This will help them to understand what they are looking for and learning. Share videos of lines of symmetry.
After whole class practice, split students into small groups. Here they will be working together to find lines of symmetry and drawing objects and shapes that have lines of symmetry. They will need paper to draw their shapes and objects on as well as showing where lines of symmtery are. Have them fold on a line of symmetry with one of the shapes they choose. They will discuss as a group why/why not specific shapes have line of symmtery.
Now students will be doing some indpendent practice to show what they have learned. In the Pages app, have the students draw lines of symmetry on the given shapes. Also, have them take the pracitce quiz about identify lines of symmetry.
Defininton of line of Symmetry: A line of symmetry is when a shape is cut in half and looks the same on both sides, it is a mirror image.
Step 4 - Assessments
Students will be assessed through questioning, small group discussions, assignments, and teacher monitoring and observations.
