Teaching phonemes - Minimal pairs

[DIA]

Hi,
I need help regarding phonemes. Could you give me some examples of the minimal pairs you'd use to teach the following for initial, medial or final location:
/ i / and / E /
/ p / and / f /
/ r / and / l /
/ r / and / h /
/ v / and / b /

I really appreciate any suggestion.
DIA

Hi DIA,

I've inserted some suggestions below.

/ i / and / E / pin and pen
/ p / and / f / pan and fan
/ r / and / l / rice and lice
/ r / and / h / rate and hate
/ v / and / b / van and ban

All the best,

Lucy
