iPads 1-5 are 5th generation, M1 processor. iPads 6-10 are 6th generation, M2 SoC processor.
All iPads come with case and Apple Pencil. The Apple Pencil can be set in the case two different ways, one charging, one not. You can look for the icons embossed in the case to see the charged lightning icon and line up the pencil accordingly. Pushed up so the lightning is visible, the pencil is charging. Pushed down so the no lightning is visible, the pencil is not charging. The Pencil is magnetic and will attach to the side of the iPad.
