Instructional Ideas

• Assign the video for pupils to watch the night before doing the assignment in class
• Provide instruction on denoting and representing a vector to make a connection to the translation vector notation

Classroom Considerations

• Vectors are a new concept for the class
• The lesson is part six in an 11-part unit on congruence and similarity

Pros

• Independent practice includes analysis of an image compared to the pre-image after a translation

Cons

• Restricts the instructional method to direct instruction
• There are no graphics in the handout for a series of transformations
