qu quit

This is the consonant q
q is always followed by u, so we teach it as qu
qu blends 2 sounds — /k/ and /w/ — to make a /kw/ sound

(There’s a practice sheet for reference for correct letter formation).

v van

This is the consonant sound /v/

/v/ is a long sound. See how long you say “vvvvvvvvvvv”

(There’s a practice sheet for reference for correct letter formation).

h hop

This is the consonant sound /h/

Most teachers call this a short sound, too, as you can’t hold the sound. It’s a quick breath of air.
