First press play to hear an arpeggio to establish the key followed by the starting note.
Press pause. Then sing the melody without the recording. This will be sung one octave lower than what is written.
Finally, play the recording to check your work.
*HINT - if you make a mistake try to keep going to keep a steady pace and get back on track where you can.
