Hi Maria,
This kind of worksheets is not enough generally.
Just add some exercises with missing vowels (dotted letters), then with missing consonants.
Add some pictures of animals with the words to match. Unscramble exercise is another idea to learn new words.
These are only few examples.
The reason why is that Latin letters exist in Italian, Spanish, French, German ... so you need to have some exercises with written English instructions even if there are only for the teachers.
I hope this will help and I am sure you will find some other ideas.
Cheers.
Maryse.
