**Vocabulary Builder** is a free course that teaches middle school students how 
English words are built, so they can work out the meaning of thousands of unfamiliar
words. Instead of memorising long word lists, learners master the building blocks:
prefixes, suffixes and **Greek and Latin roots**, along with context clues and shades
of meaning.

A large share of the academic words students meet in science, maths and social studies
come from Greek and Latin. Once you know that _bio_ means life, _graph_ means write
and _-logy_ means the study of, words like _biography_ and _biology_ stop being 
mysterious. This course gives students a toolkit they can use in every subject, 
on tests and in their own writing.

## What you will learn

 * Break words into prefixes, roots, base words and suffixes
 * Use common prefixes to change and predict word meanings
 * Use suffixes to identify parts of speech and spell new words correctly
 * Recognise 30 high-value Greek and Latin roots
 * Use five types of context clues to work out unfamiliar words
 * Choose precise words by understanding synonyms, antonyms and connotation

## Who this course is for

This course is for students in Grades 6 to 8 (about ages 11 to 14), and for older
students or English learners who want to strengthen their academic vocabulary. Learners
should be able to read grade-level texts independently.

## A note for parents and teachers

Word study works best little and often. Encourage students to keep a vocabulary 
journal and to notice word parts in their other subjects, such as _photosynthesis_
in science or _perimeter_ in maths. A good dictionary, print or online, is a useful
companion; many dictionaries list a word’s origin, which lets students check their
predictions. Note that word parts are a strong clue, not a guarantee: English has
borrowed from many languages, and some words look like they contain a prefix when
they do not.

## How the course works

There are ten lessons of about fifteen minutes each. Every lesson includes worked
examples, key takeaways and a practice exercise with answers. The final lesson helps
students build a personal word toolkit.
