Students review word formation using prefixes to enhance vocabulary. A prefix is an affix which is placed before base word. Adding it to the beginning of a word changes it into another word. For example, when the prefix dis- is added to the word appear, it creates the word disappear. A prefix is also called a preformative in the study of languages because it alters the form of the word to which it is affixed.
We use CEFR
As a great ESL teacher you need to be able to adapt your teaching style and presentation of material to suit the student’s level.
The six reference levels used by the Common European Framework of Reference (CEFR) for grading an individual’s language proficiency are A1, A2, B1, B2, C1, C2.
Our suggested levels are just an indication. Teachers should evaluate the suitability of a handout before it is taught in a class. Often, a handout is included in two levels. This is based on variations in the way it can be taught in a lesson. A Handout may be suitable as an introductory lesson for one level and a review for a higher level. The teaching notes may include suggestions on how to teach handouts to mixed level students.
