Run the 'top' command and press '1' to see the individual cores.

When runnging the top command, press f then j to display the P column (last CPU used by process), in addition to the 1 command in top, you should view some multi core occupation informations :)

htop shows you the cpu usage of each core in a graphical manner (ncurses).

You may need to parse this to use it for a presentation, or sum it But read the man page as mpstat has some useful options.
