Sample Unit 35
is a grammar practice book, based on 50 errors commonly made by students
of all language backgrounds. The units are organized into five levels
(of ten units each), according to how difficult each point is to understand.

The approach in Impact
Grammar is a "grammar awareness" approach. First, students are
guided to notice the usage of the grammar point in context. A short audio
passage (all passages are on the audio CD in the back of each book) contains
8-10 occurrences of the grammar point being featured; an exercise in the
textbook guides students to notice the occurrence of the point. Second,
students complete a table that guides them to understand the point. Third,
students are asked to formulate the grammar rule. This inductive approach,
outlined in the accompanying article by author Rod
Ellis, helps students understand grammar actively.
The sample unit
presented here features a common grammar problem, verb complements (e.g.
I enjoy playing tennis. vs. *I enjoy to play tennis.) The first step is
Listening to Comprehend. This section presents the audio passage with
comprehension questions to allow the students to focus on meaning first.
The second step is Listening to Notice. This section presents the text
in written form, with the focal grammar point blanked out, to help the
students notice its use in the passage. The third step, Understanding
the Grammar Point, guides the students in analyzing the grammar point
and constructing the underlying rules. A reference section in the back
of the book, called Grammar Explanation,
allows students to see the rules (and further examples) after they have
tried this section. The fourth section, Checking, presents new items for
the students to check their understanding. The final section, Trying It,
allows students to try out the grammar point in a communicative task.
