This is a introduction to reflection and symmetry. I'd recommend modelling on A3 paper first to the students before giving them a shot on their own. Demonstrate to students that the count the number of boxes that the line goes up from the line of symmetry and they will draw the line below going down by the same number. Eg if the first line goes up 2 boxes they use the same starting point and draw a line going down 2 boxes. As an extension when students finish the drawing they could colour it in and make sure their colour scheme is symmetrical as well. Also adding additional features on both sides will further demonstrate their knowledge of reflection and symmetry. This is the easiest of three, the other two are paid options as they are harder to put together.
