You will find that ActivInspire has TWO erasers now. The 'Magic Ink' eraser acts like a pen that can draw a 'see through' annotations on the top layer, letting you punch holes through the objects on the top layer.
On this flipchart page above, the student can use the magic eraser to 'erase' the white boxes and reveal the hidden text. See how the author of this flipchart uses Action Objects on the bottom of the page so that students can easily choose the Magic Ink tool as well as the Reset button and the Page Notes for directions.
This lesson idea comes from the DK Eyewitness series of Activpacks, Ancient Rome.
