In the first semester I used the textbook
Sounds Great 1 for Grade 1 normal school lessons.
It was a good introduction to the alphabet.
Here is the PPT's that I made for it.
Learning the ABC's is a lot of work.
The students should be able to:
Recognize the letter by sight.
Match the "big" letter with the "small" letter.
Give and recognize the phonetic sound/s of the letter.
Know words starting with the letter.
And write the letter. (I teach this by first drawing the letter with their fingers in the air.)

good luck
(Some of these power points have grids filled with the vocab pictures - print them and use them as flashcards.)
