On your iPad go to SETTINGS. On the right hand side towards the middle of the page, make sure that you switch MULTITASKING GESTURES to ON
Using all 5 fingers, you can PINCH to get to your home screen, SWIPE UP to get your multitasking bar, SWIPE LEFT or RIGHT to switch between apps. See video on the next step.
In this video I will go through the 3 different gestures WITHOUT using my Home Button.
