Do your best as a teacher to make sure students are expanding their vocabulary on every occasion.
Expanding vocabulary
Expanding students' vocabulary is an important part of the learning process.
It is unacceptable when after a few classes your students still say, "I need that blue thing or the red part".
Practice makes perfect
The teacher should encourage students to pronounce the names of the parts on every occasion.
This is easy when students ask you to give them some part from the set or ask you to help them find a piece in the set.
