It just asks you to write 1 2 3 below each note from 1 through 4. At number 3, add the 3/4 time signature after the clef. At number 4, do the same thing at number 3 but make sure each measure has three beats. it can be easy if you start by writing the 1 2 3 below each note like they shown above.
I would say form, texture and color for this piece but mostly focused on texture
