Bring a set of ABC letters to be glued down onto the poster.
Put the set in the centre of the table. Or each child may have a separate set of ABC letters.
Say any word known to children and ask children to find the first letter of this word and glue it down onto the poster in an approximate alphabetic order.
The one who has the best glued letters in a correct alphabetic order is a winner. If it is difficult let the kids glue letters down at random.
Ask them at the end to pronounce these letters and draw the pictures of these words at home.
