If we compare PPP and TBL, we can easily identify the same stages:
A) doing a task using the target language to focus on meaning
B) getting the necessary information about the target language (either through the teacher or by discovering it for yourself), analyzing its meaning and form
C) encountering the target language (in a model dialogue, in texts for listening and reading, or through prompts supplied by the teacher)
D) Doing language-focused activities to focus on form
In the PPP lesson model, this sequence looks like this CBDA.
In the TBL lesson model, this sequence is ACBD.
