Mickie may need some of these files too although her group may be behind Group 1 in English.
Most of them need a lot of practiced on handwriting.
This includes writing their names in Thai and English and writing the 32 Thai consonants.
Nam: the two files below are new in Thai Alphabet:
You should try to get them to do well on the file Thai Alphabet Consonant Sets 1, 2 and 3 Test on Writing Letters (32)(answers) PDF where they have to write the 32 randomly dictated Thai consonants on the answer sheet Thai Alphabet Consonant Sets 1, 2 and 3 Test on Writing Letters (32)(answer sheet) PDF
Nam the file Thai Alphabet Consonant Sets 1, 2 and 3 Test on Letters (32)(ordered) PDF has a correction in it
They can do some tracing at home too.
You can try to teach counting to 100 in both Thai and English too. They could start counting to 30 if needed.
Attached are some files that may be useful.
They could also try to write English capital letters. I assume that most in Group 1 at least can recognize up to 26 English letters.
I have attached several English alphabet tests too if they are ready for these
Also some handwriting lessons
