120 Root Words, Prefixes, and Suffixes PDF List
120 Commonly Used Roots, Prefixes, and Suffixes

The English language is filled with words borrowed from ancient Greek and Latin, which makes supplementing your instruction with word parts practice that much more critical.  There are countless ways to incorporate word parts into your lesson plans. You may already have a structured plan in place, or you might be testing the waters. Either way, teach your students to be word detectives.  A word detective looks at all the clues to determine a word’s meaning. When students know how to decode large words by identifying root words and affixes, they will be sufficiently prepared to tackle higher level texts. 

The table below lists 120 commonly used Greek and Latin root words, prefixes, and suffixes.  It also includes the meaning of each word part and several example words. It’s a great place to start if you’re interested in adding a regularly scheduled word parts practice to your daily teaching agenda.

How old is your child? Critical Thinking Word Roots appears to be for gr 5 and above. The other three books you listed can be used from gr 2 onwards.

You can see the entire Vocabulary Packets : Prefixes and Suffixes book at Scholastic’s store. It looks boring, because each unit teaches the same 12 words over 4-5 pages (i.e. 3 words per prefix or suffix). Also, the games are more suitable for a classroom. If you are sure you can extend the knowledge of those prefixes and suffixes to more words during your read-alouds or teaching sessions, then it is an inexpensive option (I used the coupon code 10THANKS).

Also, with the Scholastic Prefixes and Suffixes book, you will need the Vocabulary Packets : Greek and Latin Roots book.

page 1: introduce 10 words for the root

page 2: match word with meaning (you have to print and cut out the cards on this page)

page 4: quiz (bubble test for the meaning of each word)

I’d say the Learning Works books are more suitable for a homeschool than the Scholastic books are.

Based on samples of Red Hot Root Words on Amazon, I’d say it looks much more fun. Get the book 2 only — book 1 has the same roots as book 2 but at a more basic level.

Have you seen Words On the Vine? It seems to be the most humourous and interesting of all word root books I have seen and it is the most inexpensive too. I would suggest this for a start.
