Rotation ppt description This PowerPoint is eight slides long and introduces one of transformation (rotation) to intermediate students. Slide #3 introduces the rules for rotation about origin in the counter-clockwise direction at three angles (90°, 180°, and 270°). In order to achieve a clockwise direction just reverse the rules for 90°, and 270°; the rule for 180° remains the same. I give a reference sheet that has the rules. Slide #4 illustrates the 270° and 90° are the same rotation. Some

Reflection ppt description This PowerPoint is eight slides long and introduces one of transformation (reflection) to intermediate students. Slide #3 stresses the change in orientation. Slide #4 shows that figure and its reflection are equally spaced from the line of reflection. Slides #5 and 6 illustrates how to find the line of reflection by dividing the range between reflecting points by two. Many students do this but they don’t know how to explain it. The exit question slide reviews thre

Translation ppt description This PowerPoint is eight slides long and introduces one of transformation (translation) to intermediate students. Slide #4 stresses the horizontal and vertical movement of each point. Slide #5 and 6 introduces the correct labeling “prime and double prime”. The exit question slide reviews three concepts that I wanted to stress; vocabulary, horizontal & vertical movement, and labeling. This is short and sweet but if students understand this, they should have success
