Thanks to user 'stipton' for this great PPT. I have adapted it and added audio narration and some extra slides at the end which explain the difference between upper and lower case letters and when students should use capital letters.
The above printable, downloadable handout is recommended for at Beginner (pre-A1) level. It is great for revising Punctuation in English, and is excellent for enhancing your groups' Reading skills. It is about the vocabulary topic of Alphabet.
