Pathing for Shaco can be a little weird at times. If you are starting red buff use jack in the boxes on the red before it spawns. Kill the red with the help of the jack in the boxes w/o using smite then move on to krugs by leveling q and hopping over the wall. Smite the krugs and use your abilities to kill as fast as possible by using q to get backstab bonuses and using the box to cc them. After krugs move to raptors and start by killing them with the box. Focus the largest raptor first with autos while your box kills the smaller ones. Move towards the bottom jungle next and start wolves the same way as the raptors. Kill blue the same way you killed the others. Use smite on gromp to start then killit. From here you can decide to kill scuttle crab then gank bot or mid, or you can back.

Blue start is practically the same. Start blue the same way you started red and then move onto gromp w/q and start it with smite. Move onto wolves , box them and kill them. Move onto raptors box them focus big raptor. Kill red w/o smite then q over the wall again to kill the krugs by smiting first. Again here you can chose to kill scuttle or move onto ganking mid or top, or killing the scuttle and backing.

After using smite five times ,your jungle item dissapears fusing into your smite ability keeping the stats the item came with. Your smite becomes augmented with a frost passive which allows you to slow down the enemy champions for a kill. Try using your smite to kill them when you know objectives aren't up and you have time to use it.
