Lesson objective: Solve problems using knowledge of rigid transformations.

This lesson provides an opportunity for students to apply their knowledge and understanding of the connection between parallel lines and rigid transformations to a real-life situation. Students are asked to use the properties of rotations, reflections, and translations to describe a pattern that can be made while meeting specific requirements.

Key Concept students will use:

• Parallel lines are taken to parallel lines when rotated, reflected, or translated because the distance between the lines is maintained.

Skills students will use:

• determining if lines are parallel (Grade 4, Unit 13)
• verbally describing rotations, reflections, and translations
• recognizing what an image will look like after a specific transformation

Students engage in Mathematical Practice 4 (Model with Mathematics) as they apply their knowledge of rigid transformations to a real-life task.

Key vocabulary:

• parallel
• reflection
• rotation
• translation
