Are there any resources that provide a list of morphemes to teach at each K-5 grade level? I have been looking for a definitive list of morphemes that is organized by grade level like the Fry sight word list. I often come across research about how L1 and L2 students acquire morphemes, but I am looking for a list that represents the morphemes that students will most likely see in print at each K-5 grade level. Does anything like that exist? Thank you for your time.
The short answer to this question is, “No, I don’t know of such a list.”
But when have I ever been satisfied with the short answer to anything?
Let’s make sure we’re all in agreement as to what constitutes a morpheme? Basically, a morpheme is the “smallest grammatical unit.” It isn’t the same thing as a word, and yet many words are morphemes. The distinction turns on whether the unit (the morpheme or word) can stand on its own. Words have to have that kind of independence, while morphemes don’t require it.
Thus, bags, trucked, running, and redirect are all words in the English language while bag, s, truck, ed, run, ing, re, and direct are all morphemes. Each morphemic unit carries meaning, but sometimes morphemes can do that independently (bag, truck, run, direct), and sometimes they need to be combined with other morphemes to be considered a word (s, ed, ing, re).
I admitted ignorance on this issue, and I’ve tried to turn that ignorance to your advantage. I contacted Jeffrey and Peter Bowers. Both are outstanding scholars (Jeff at the University of Bristol in the UK, and Peter at WordWorks Literacy Centre, in Ontario) who are particularly knowledgeable about teaching morphology to improve literacy. They’ve both published widely on the issue, and both have chided me when they felt I wasn’t paying sufficient attention to how words work morphologically. These days I know no one better able to provide you with a thoughtful answer to your question, and boy was I right! I apologize for the poor renditions of the Word Matrix and the Word Sums. I'll be working with my webmaster to get the real graphics in, but in the meantime you can go to the Word Works website to see them in their full glory. http://www.wordworkskingston.com/WordWorks/Home.html
Word Matrix: A map of a word family
Word Sums: reveal underlying structure of any complex word (a word with more than just a base)
Here is Peter Bower’s response (with my light editing):
“I have no knowledge of such a list, but I wouldn’t recommend one anyway.
“My recommendation based on theory not direct research evidence — is that the main value comes from teaching all or many members of a morphological family at one time with the matrix and word sums (see the attached figure illustrating a matrix and word sum). In the younger grades I start with free bases [those morphemes that stand alone as words], but once that is established, I have no trouble introducing bound bases [the units that can’t stand alone]. This relates to the research we cite about the value of studying meaningfully related items at one time rather than disconnected items.
“Instead of a “scope and sequence” of morphemes to teach, what I recommend is starting with words in the children’s vocabulary, analyzing such words to find their bases, then looking for other members of that family.
“The point is not that there is a “scope and sequence” of morphemes to teach. Rather there is a kind of a “scope” of orthographic concepts that we want students to learn, and teachers can address those concepts based on whatever words are central to the readings they are introducing to the students.
“A brief list of those concepts that should be taught would include:
“If we are going to teach children how their writing system works, we need to teach them the interrelation of morphology, phonology, and etymology. As we have pointed out, this is why Structured Word Inquiry (SWI) is not about “adding” morphological instruction to phonics instruction — its about teaching how the system works. This is why I argue that SWI teaches grapheme-phoneme correspondences more explicitly and accurately than phonics. Phonics instruction (under the definition of associations of pronunciations and letters without reference to morphology or etymology) cannot explain the grapheme-phoneme correspondences in countless words like does or rough or every or homophones, and so on. So many people miss the absolute detail into orthographic phonology that comes with SWI.
“Here are some videos to illustrate my point:
“It’s as simple as starting with the “known” and then expanding from that. Even if kids know all the words in a morphological family (e.g. play, playing, playful, replay, playhouse) the lesson is not about new vocabulary, but learning how word structure links words. That concept can then be applied anywhere.
“The other thing I keep in mind when choosing morphological families to investigate is the orthographic concepts a family has to offer. If I’ve established the fact that words that share a base share a spelling and a meaning connection, then I can introduce a base like with words like actor, acting, react, and action as a way to introduce the fact that the pronunciation of morpheme might change but keep the spelling. In that way we learn the phonology of t is not the “t sound”, but that the grapheme can write /t/ when that is the appropriate sound. I’ve attached an example of a lesson I’ve used for that before.
“I also draw on the <-ed> suffix from early on to highlight this same concept that morphemes do not have pronunciations until they are in a word. The pronunciation of a word like is another useful one to get rid of this idea of a “t sound” since this very common pronunciation of a very common suffix is what is typically thought of the “t sound,” but their ain’t no /t/!
“And then you also encounter words that give rise to the need to teach all the suffixing changes.
“These are concepts teachers need to learn and they can bring into work with their class as they investigate words.”
I don’t disagree with Peter on any of this, except I’m not as dismissive of the kind of list that you are requesting. I don’t see it as mutually exclusive from the curriculum goals that he specified or contradictory of the kind of instruction he described.
Many teachers, when referring to morphology or “structural analysis”, actually are talking about affixes alone, and not the bases. If that is the case here, there are some lists like that which present the most common prefixes and suffixes from textbooks in grades 3-9 (White, Sowell, & Yanagihara, 1989). You can easily find those lists on line and you could definitely make use of those lists to make sure that you are hitting all the notes if you do the word sums and matrixes that Peter recommends.
Otherwise, I haven’t been able to come up with a graded list of bases for you to use. But I have passed your letter along to my friends at MetaMetrics (the Lexile people) and have asked if they could produce such a list from their language corpus of more than 1 billion words. Stay tuned!
