Transum,
The Starter called Cat Face may be more suitable for your class. It is more of a standard reflection activity with controls to allow the teacher to select vertical, horizontal or a diagonal mirror line. There is also a choice of four different comic faces intended to motivate pupils to make a good job of the task. Transum subscribers also have access to a button which superimposes the answers onto the diagram.

Teacher, do your students have access to computers such as tablets, iPads or Laptops? This page was really designed for projection on a whiteboard but if you really want the students to have access to it here is a concise URL for a version of this page without the comments:

However it would be better to assign one of the student interactive activities below.
