Letrs Unit 3 Session 1: A Plain Walkthrough
Letrs Unit 3 Session 1 is the opening session of the "Foundations of Word Recognition" strand in the Language Essentials for Teachers of Reading and Spelling program. It covers phonological awareness, specifically the shift from oral language skills to print-based decoding. The session is short — roughly 45 minutes of video and associated activities — but it establishes the framework that every subsequent lesson builds on. If you're going through this as part of your state-mandated literacy certification, you'll hit it around the middle of the course. The session itself breaks down into two main parts. First, there's a detailed review of phonological awareness sub-skills: phoneme blending, segmenting, and manipulation. Second, it connects those oral language skills to alphabetic principle and introduces the concept of phonemic awareness as the critical bridge between hearing sounds and mapping them to letters. The activity worksheets are minimal. Most of your time will be spent watching the presenter, answering discussion prompts in the Participant Guide, and completing the self-assessment quiz at the end.
Letrs Unit 3 Session 1: What Actually Happens and How to Get Through It
I'll be honest about how this session works in practice. The video presentations are well-made but dense. The presenter moves quickly through terminology, and if you're not already comfortable with terms like phoneme, syllable, onset-rime, and morpheme, you will fall behind within the first ten minutes. I've seen this happen repeatedly with teachers who are new to the science of reading framework. The most useful thing you can do before watching the video is skim the Participant Guide pages for Session 1. Don't take notes yet. Just read through the key terms and the activity instructions. This takes about five minutes and prevents that moment during the video where you're frantically flipping back pages trying to remember what "phoneme segmentation" means. The activities themselves are straightforward. You'll listen to audio recordings and identify spoken phonemes, then complete a chart mapping sounds to their corresponding graphemes. The trick is that the audio examples include dialectal variations — some speakers blend sounds differently, use different vowel pronunciations, or drop final consonants. The test isn't whether you can identify sounds in standard American English; it's whether you can recognize that dialect doesn't change the underlying phonological system. I ran into this exact issue during my own coursework. One of the audio clips featured a speaker with a Southern accent pronouncing "ride" as something closer to "rahd." The expected answer was still the /r/ /ī/ /d/ phoneme sequence, but my initial instinct was to write it out phonetically as I heard it. I got the question wrong the first time, corrected myself, and now I go into these activities knowing the task is to identify abstract phonemes, not transcribe dialect.
Here's a counter-intuitive point that most people miss: the phonological awareness section is not the hardest part of this session. The easiest part is also the most easily glossed over, and that's a mistake. Teachers often rush through the blending and segmenting activities because they feel like they already know this stuff. But the session's real purpose is establishing that phonemic awareness is a continuum, not a binary skill. A student can blend sounds perfectly but cannot segment them. These are separate neural processes, and the assessment data from this session will show you exactly where each of your students falls on that spectrum. If you skip the nuance here, Unit 3 Session 2 — which moves into phonics instruction — will feel much harder than it needs to be. Another thing worth noting is that the self-assessment at the end of the session includes questions that are deliberately tricky. They present a word like "ship" and ask you to count the phonemes. The answer is four: /sh/ /ĭ/ /p/ — not three, because "sh" is a single phoneme represented by two letters. This trips up a surprising number of people who haven't internalized the difference between letters and sounds. Do not second-guess yourself on these. Trust the distinction between phonemes and graphemes that the session establishes earlier. The entire session, including video time and activities, should take you between 60 and 90 minutes if you're working through it carefully. Budget more if you're encountering the terminology for the first time. The worksheets can be printed from the Letrs portal or completed digitally, depending on your platform. There's no downloadable PDF you can grab externally — everything lives inside the Letrs system, which is intentional and by design.

A word of caution: don't try to speed through this session to get to the "real" phonics content. The phonological awareness foundation is where a lot of struggling readers break down, and understanding the diagnostic markers from Session 1 will directly improve how you teach the decoding skills that come later. I've watched colleagues who treated this session as a formality struggle significantly in Unit 4 when they couldn't diagnose why a student was failing at phonemic manipulation tasks. The material is sequential for a reason. If you need the participant guide or any supplemental materials, they're available through the official Letrs portal at learnletds.com after you've enrolled in the course. There's no legitimate third-party source for these materials, and anything claiming to offer them outside the official channel is likely distributing pirated content.
