With student review various reflections, translations and rotations in Worksheet 1 (Braille the sheet prior to working with the student) If needed use the Swing Cell or peg slate. The swing cell can be especially helpful with rotations.
When the student is confident, have them find rotations, reflections and translations using the instructions in the "Finding Transformations" document. The student shoud use their media of choice. Some students who are very familiar with braille may be able to identify the transformations mentally. If the student needs more support or if the student uses large print, different options for completing the assignment follow.
Braille students: enlarge the copy of "Letters and Contractions" worksheet onto cardstock paper/braille paper. Using dots (or other tractile product such as Wikki Stix or puffy paint) create the letter/contractions. Cut out the individual letters/contractions and have the student mainuplate the individual cut out cells until they identify the rotations, reflections and translations.
Large print students: enlarge the copy of "Letters and Contractions" worksheet onto cardstock paper/braille paper. Cut out the individual letters/contractions and have the student manipulate the individual cut out cells.
The student does not need to know or understand braille in order to participate in this lesson although it is helpful. The purpose of the lesson is to identify refelctions, translations and rotations.
Braille students should complete the assignment using the Perkins Brailler or any other means of producing braille output.
