1. Transformation, Translation, Reflection, and Rotation Kristin Gibson

2. TEKS TEKS for this third grade transformation activity is: (1) Mathematical process standards. The student uses mathematical processes to acquire and demonstrate mathematical understanding. The student is expected to: (G) display, explain, and justify mathematical ideas and arguments using precise mathematical language in written or oral communication

3. What is Transformation? Transformation involves rotation, reflection, and translation. After any of those transformations the shape still has the same size, area, angles, and line lengths.

4. Example of Transformation

5. Transformed figure http://www.sheppardsoftware.com/mathgames/geometry/shapesho ot/TranslateShapesShoot.htm http://www.sheppardsoftware.com/mathgames/geometry/shapesho ot/TranslateShapesShoot.htm View link above! The link allows students to play a game that involves the different types of transformations.

6. What is Translation? A translation is a motion of a plane that moves every point of the plane a specified distance in a specified direction along a straight line.

7. Example of Translation

8. Translated Figure http://www.mathwarehouse.com/transformations/translations- interactive-activity.php http://www.mathwarehouse.com/transformations/translations- interactive-activity.php View link above! The student will practice this activity and gain knowledge on how to translate.

9. What is Reflection? A reflection involves flipping an object across a line without changing its size or shape.

10. Example of Reflection

11. Reflected Figure http://www.active-maths.co.uk/whiteboard/reflect_shapes.html View this link of a Reflection activity

12. What is Rotation? A rotation is a transformation of the plane determined by holding one point-the center- fixed and rotating the plane about this point by a certain amount in a certain direction

13. Example of Rotation

14. Rotated Figure http://www.mathsisfun.com/geometry/rotation.html View link above! This shows an example of a figure rotating.
