Here there are four 6/8 time signature exercises, so, if you recall the theory video, you have to use the 2/4 hand movement to measure the bars. The first exercise has got a metronome sound to help you be accurate with measuring the time and mark the subdivision of each beat into three  (compound triple) . For exercises 2, 3, 4 you can use the metronome sound below (there are two bar rests at the beginning so, even though the exercises have got eight bars, the metronome sound has got ten). Remember the notes in this link.   

First study the scores and practise hand movements to represent the corresponding time signature. Then name the notes aloud while keeping the beat with your hand. It doesn't matter if you start slowly, the idea is that speed is increased with practice.
