K-5 classroom teachers, special educators, and any middle/high school teacher in a high-poverty school where oral language gaps are wide.
Below is a detailed, long-form review written from the perspective of an experienced literacy coach and LETRS facilitator. Review by: A Literacy Coach & LETRS Facilitator Introduction: Why Resource 5.3 Matters Anyone who has completed LETRS (Louisa Moats, Ed.D., & Carol Tolman, Ph.D.) knows that the "resource lists" are not mere appendices; they are the tactical field guides for the classroom. After the theoretical heavy lifting of Units 1-4 (phonology, phonics, fluency), Unit 5 arrives with a sobering fact: Vocabulary is the single best predictor of reading comprehension. Yet, it is often the most poorly taught component.
Resource 5.3 is not just a list; it’s a process. It explicitly reminds teachers to check for morphemes (roots, prefixes, suffixes). For example, before teaching unfortunate , the list prompts: Can students use 'un-' (not) + 'fortunate' (lucky)? If yes, move that word to incidental instruction and save explicit time for absurd .
This is an excellent request, as it touches on the core practical application of the LETRS (Language Essentials for Teachers of Reading and Spelling) framework. A thorough review of requires situating it within the broader LETRS context, specifically Volume 1, Unit 5, which focuses on "The Mighty Word: Oral Language and Vocabulary." resource list 5.3 of the letrs manual
—often titled "Considerations for Selecting Words for Explicit Instruction" or a similar variation depending on the LETRS edition (1st vs. 2nd)—is the Rosetta Stone between research and reality. It answers the dreaded teacher question: "Which words do I actually have time to teach?"
is arguably the single most practical tool in the entire LETRS manual for improving reading comprehension. It moves vocabulary instruction from "look it up" to strategic, cognitive science-based triage. If every teacher in America used this list to select their weekly vocabulary words, the gap in academic language between advantaged and disadvantaged students would narrow significantly.
A subtle but powerful section of 5.3 addresses ELLs. It notes that Tier 1 words for a native speaker may be Tier 2 for an ELL. The list includes a fourth, unspoken tier: Tier 1.5 – common words that are not pictorial (e.g., bring, carry, follow ). This prevents the tragic error of ignoring basic prepositions for ELLs. Part 3: Where the List Falls Short (Critical Limitations) No resource is perfect. In the four years I have facilitated LETRS training, the most common teacher complaints about Resource 5.3 are these: After the theoretical heavy lifting of Units 1-4
The list typically breaks down into three columns:
ESL specialists (who need to modify the Tier 1 assumptions), and kindergarten teachers (where almost all words are Tier 1, making the list less relevant until late first grade).
| Tier | Description (per LETRS 5.3) | Examples | Instructional Priority | | :--- | :--- | :--- | :--- | | | Basic, everyday words. Rarely need instruction for native speakers. | clock, baby, happy, run | None (except for ELLs) | | Tier 2 | High-frequency, cross-curricular academic words. Mature language users. The sweet spot . | coincidence, absurd, fortunate, analyze, establish | Highest Priority | | Tier 3 | Low-frequency, domain-specific words. Best taught in context of a lesson. | photosynthesis, isthmus, pentameter, amortization | Contextual / Just-in-time | It explicitly reminds teachers to check for morphemes
Using Resource 5.3 faithfully means doing a word-level audit of every passage before teaching. For a middle school ELA teacher with 120 students and three preps, this is unsustainable. The list is research-perfect but pragmatically exhausting. LETRS acknowledges this but doesn't offer enough tech integration (e.g., automated text analyzers). Part 4: A Case Study – Applying Resource 5.3 to a Real Text Let’s test the list on a sentence from The Outsiders by S.E. Hinton: "I was reluctant to sass Darry, but he was being so unreasonable ." Step 1 – Identify potential words: reluctant, sass, unreasonable.
The list assumes that if a word is Tier 3 (e.g., monarchy ), students can learn it via context. But a student who has no schema for kings, queens, or succession will flounder. Resource 5.3 needs a stronger caution: Tier 3 words that are conceptually dense should be pre-taught explicitly, even if they are low frequency. The list is slightly too rigid.
