Although I certainly haven't finished the project, I'm off to a good start at last. The list I'm using as a base for freshman vocabulary comes from 100 Words a High School Freshman Should Know on vocabulary.com. Some words on the list seem fairly basic (like camouflage), but can students use the word camouflage to describe the pattern of fur on a wildcat, or do they think it only applies to a military-inspired, splotchy green pattern of fabric? And for ESL students, this may be the first exposure to the word.
This is only part of an effective vocabulary curriculum. I hope it helps engage students visually with words that might otherwise seem abstract. Be sure to let me know how it goes!
