1. Expanding students' vocabulary and having fun too!! By Marlene Chesney

2. Vocabulary What does it mean to ‘know’ a word?
Word meaning is not as obvious as it sounds. Shanker & Cockrum (2009) suggests five different levels of vocabulary knowledge, listed here from lowest to highest.
A student has
no recall of the word, and may never have come across it before.
no idea of its meaning, but is aware it is a word.
a rough idea of its meaning and understands the word in context.
a thorough understanding of the word in the context in which it appears.
a knowledge of the many meanings of the word
(if applicable) and integrates the word into speech, writing and thought.

3. When one reads, there is a finite amount of cognitive resources available to both decode the words and then gain meaning from the reading.
If too much of these mental resources are required to decode the word, then comprehension may suffer.
(LaBerge & Samuels’s theory of automatic information processing,cited in Rasinski & Hoffman, 2006).

4. A vocabulary enhancement strategy…..
Many words in English are based on
Latin roots, Greek combining forms and Anglo-Saxon base words.
Added to these are prefixes and suffixes, which form new words.

5. What are the most common prefixes and suffixes in English
What are the most common prefixes and suffixes in English? Note : the word affix means prefixes and suffixes

6. Most common Prefixes & Suffixes
Dis
In, im, il, ir Re un
-ed
-ing
-er,-or
-s, -es
In printed school English, 97% of prefixed words and 97% of suffixed words have the above endings.

7. Most common Prefixes & Suffixes
Dis…………not
In, im, il, ir..not
Re……..again, back
Un……..not
-ed...past tense-verbs
-ing…verb form/present participle
-er, or..person connected with
-s, -es…plural
In printed school English,
97% of prefixed words and 97% of suffixed words have the above endings.
Note that the suffixes –ed and –ing CHANGE the part of speech or tense..they are called “INFLEXIONAL ENDINGS”.
-er, -or, are DERIVATIONAL SUFFIXES..they change the MEANING eg actor. waiter

28. Greek Combining Forms
Many of the Latin roots were actually borrowed from the Greek.
The Greek –based words in English tend to be related to math and science.
Note: Because Greek-based words part compound, the parts are usually called combining forms.

31. Brainstorming Greek-based words
Students write as many words containing each Greek combining form as they can. This can be a group or solo activity
