Here is a website that will help you build your vocabulary.
The site has audio activities to help you learn new words. A definition of the word, the part of speech, and the word in a sentence are provided for each example to expand your vocabulary, which will improve your STAR Reading level.
Some PowerPoints will be provided below taking the information and putting all of it in one place.
You should master ALL of these words by your junior year of high school to prepare for the SAT, a test taken to measure your academic IQ. Universities normally look at your SAT scores and your grades as benchmarks for college acceptance.
