What makes the family topic different is that children are talking about themselves for the first time, not about a cat in a book. That connection is why the words stick. It also makes the topic a delicate one: every classroom has children whose family doesn't look like the family in the textbook. Word the task openly, "draw the people at your house" rather than "draw your parents", and nobody has to feel awkward.
The core words, in the order to teach them
- The core: father, mother, brother, sister, plus the everyday dad and mom that children will actually hear far more often.
- Widening the circle: grandfather, grandmother, baby.
- Grade 3: uncle, aunt, cousin. Here the topic gets genuinely fun, because Thai names relatives far more precisely than English does. Children are amazed that the single word uncle covers lung, naa and aa, three relatives Thai keeps carefully apart.
The anchor activity: build your own family tree
Have each child draw their own family tree and label every person in English. Then they come to the front and introduce them with a set frame: This is my mother. Her name is Nid. One piece of work covers everything at once, vocabulary, writing, speaking, and the pride of getting to tell the class about your own home.
Finish with matching and gap-fill worksheets, so you know they can read the words away from the safety of their own drawing.
