The learning curve of your child is improving and his school has started including letter making in his curriculum. As a parent you should also contribute to his learning by helping him understand the sound of every letter he's making. Speak with him while he's trying to make a word.
Teach him how every letter sounds, by speaking it slowly and a sound gesture that will make phonetic clear to him.
What you need to know
Play sounds with words and how to pronounce them properly. Kids learn quickly with music and sounds as they enjoy it while learning at the same time. Correct them when they speak it wrong but with politeness to make learning fun for them.
