Put a to die for treat in his crate every time he goes in. Esp if you'll be gone for a while put a kong full of goodies in it and freeze it for longer fun. If you are worried about calories it can even be his meal mixed with some broth or something that will freeze. Plug the ends with non sweetened peanut butter.
Start training by putting a treat in the crate and have him get it and come right back out. Then when he does that 80% of the time use a word cue like kennel. After he gets the word you can say the word-if he goes in then you hand him the treat. You just went from lure to reward!! Very important. I always hide food in the crate or put something great in there. Sometimes with a kong I'll put a piece of turkey lunch meat (which is the BEST) and she's usually waiting to go in eagerly.
There is a great DVD called Crate Games that is also a good way to train. I think it's on Amazon, if not then on Dogwise. There's a good vid about the difference between lure/treat/shaping that demonstrates too a nice way to get your dog to go to his crate.

Or just google kong recipes. Just be aware there are some human foods dogs should not eat. If you're not sure you can google that or ask back here for help. Examples are
grapes/raisins. The first link blueboy, has a bad foods link at the bottom it wasn't working today, maybe under construction. This one seems pretty comprehensive

Realize too he's going to cry and SCREAM a bit because he's a puppy. Esp the younger he is when you get him the harder it is to self entertain. His crate should be in the bedroom at night so he can hear you and you can hear if he needs to go out. And he may need to go out 1-2 times a night until he's 6-9 mos, longer if a small breed dog. They don't have control over those muscles until 9 or so mos. I have two crates. One in the bedroom and one in the family room for when we eat or cook etc and I can't watch 100% but puppy is still in with us and can see and hear.
Last suggestion is an X-pen sold at most pet stores. It's a bit bigger but no bottom so a tile floor with a pee pad would be a good idea if you use it. Either that or wait until puppy is older or be sure and take him out often enough.
