Christmas 1966: many of my friends & I got pellet guns as gifts. Mine was a Benjamin pump(model 310, smoothbore BB/.177), those received by the guys included several other brands & models, and one guy got the Crosman short-stroke pump-up. It was a fairly new model, his was the first one I ever saw, think it was called the 760 even then, & is the direct ancestor of the 760 you just bought. Though they've changed some things & cheaped 'em down several times over the years, they are still good value for the money.
Your new one has a smoothbore barrel, but here's a tip: try some roundnosed(or maybe pointed too) .177 pellets in it. You may be surprised at how accurate it is- the shuttlecock effect is real, & works better than you might think. The flat-nosed wadcutter types never did well in my old Benjamin, YMMV.
If you ever want to search for airgun forums, you might start by googling "green crosman forum" & "yellow airgun forum". There are lots of others too.
Hope you & your kids enjoy the new pellet gun. Be careful & shoot safe.
