This activity is designed to build context before we dive into a new math unit. In this unit- Transformations, students were given about 25 images of rotation, reflection, translation and Cartesian planes. Working in small groups of 2-3, students looked at the images (in a pile at the front of the classroom) and searched for the ones they thought corresponded to their poster topic. Once all the pictures from the original pile were selected, students then glued them on, drew lines of reflection or rotation, translation arrows or x and y axis and described where the object might be used in real life, and how the math helped to explain movement. Presentations to the class helped to show misconceptions (for example- the rotation of the umbrella was not about the outside but the pole that was being held as a point of rotation).
