Ollie:To do an ollie place your index finger on the Tech Deck symbol in the middle of your board and place your middle finger on the tail of your board.Pop the board up with your middle finger and slide your index finger up the board if done correctly you should have lifted the entire board of the ground.
Kickflip:To do a kickflip put your fingers in the same position as an ollie except place your middle finger on the edge of the tail. if you did it right you shoudl have done a kickflip (sometimes it might turn out as a varial kickflip or something though)
pop-shove-it:To do a pop-shove-it position your fingers as if doing a kickflip except place your middle finger on the top edge of the tail pop it up let go and land.You should have done a pop-shove-it if all went well.practice it to learn how hard you have to pop the board up.
Nollie:Same as an ollie but backwards.So you skate backwards and pop it up with your middle finger then while its popped up slide your index finger up the board.
