Who Can See Who? - Directions
Using the Who Can See Who? Concept Builder is quite simple. You will be presented with a plane mirror, five objects, and an eye position. You have to identify the five image locations. You also have to identify the images that can be seen from the given eye position. The Concept Builder will step you through the process beginning with the locating of the images. To locate an image simply tap on the grid in the region behind the mirror. You will be given immediate feedback if your answer is incorrect. Keep trying until you get it correct. You will begin with the image of Object A and progress in alphabetical order until you dietermine the location of the image of Object E. Once all images have been located, you must determine which can be seen from the given eye position. You do so by tapping on the letters to the right of the mirror and attached grids. Tapping once will select Visible. Tapping a second time will select Not Visible. Each consecutive tap thereafter will toggle back and forth between the two options. Once you have selected Visible or Not Visible for all five objects, a Check Answer button will appear. If you are satisfied with your answers, tap on the Check Answer button. Your answer will be evaluated and your Progress Report will be updated.
Your goal is to earn "Stars" and to complete one or more difficulty levels. Stars are earned when you show success on a particular question. Once you show success on all the questions for a particular difficulty level, you will earn the trophy for that level.
