This Instructional Activity is a part of the Lesson 2, Unit 1, Grade 8. This activity informally introduces refllections, which appear in addition to some translations and rotations (that were introduced informally in the previous lesson). Students are given a 6-frame cartoon showing the change in position of a polygon. As in the previous lesson, they describe the moves, but this time there are reflections, which may seem impossible as physical moves unless you allow the shape to leave the plane. Students identify the new moves and try to describe them. After the end of this activity, the three basic moves have been introduced and the next activity will introduce their names (translations, rotations, and reflections).
