The activities in these books are specially designed to make use of important
learning conditions. Firstly, the words are introduced using sentence definitions
and an example sentence. The activities that follow in the units encourage learners
to recall the meanings and forms of the words. Some activities also make the
learners think about the meaning of the words in the context of a sentence—a
sentence different from the sentences that occurred in the introduction of the words.
Moreover, each unit ends with a story containing the target words. While reading
the story, the learners have to recall the meanings of the words and suit them to the
context of the story. Such activities help learners develop a better understanding of
a common meaning for a given word which fits the different uses.
