It includes all the vocabulary from the first and second grades of elementary school, plus additional words recommended for those grades: the spelling of words, their origin (where necessary, to help children learn how to spell them), their analysis into components (if they are compound words) and their related words.

In addition, the words are given in sentences so that the child can consolidate their meaning and, in this way, practice their reading skills.

There are two levels of difficulty.

The game cards are structured so that they can be used:

be played by children together, in three different ways;
be played by a parent or teacher with a child;
be used by a teacher in the classroom;
be read by the child alone (using the flashcard method).
