Oral Reading Fluency Scoring Rubric
Target Rate: 45–65 WCPM for Grade 1–2
Level 3: Detective Master
Reads accurately (≥95%), observes punctuation, phrases words into meaningful chunks, reads dialogue with expression.
Interactive Case Clues: Project Slide 6. Have student detectives whisper-read each clue. Ask: "What pattern is giving this word its sound power?" Call volunteers to circle digraphs or box magic 'e' on the interactive board.
Whiteboard Word Transformations: Call out word pairs: pin → pine, hop → hope, tub → tube. Students hold up whiteboards simultaneously on the cue: "Reveal the evidence!"
Students work on the Sound Sleuths Practice Worksheet (Parts 1–4). Circulate with teacher answer key to perform quick formative checks and provide real-time reinforcement.
Paired Decodable Reading:
Partners take turns reading chapters in the Secret Dock Decodable Reader. Partner 1 reads Chapter 1 while Partner 2 listens for accurate vowel sounds, then switch for Chapter 2.
Multi-Tiered Differentiation Strategies
Tier 3: Intensive Support
Use 3-box Elkonin sound mats with physical felt tokens.
Limit word choices to CVC vs CVCe minimal pairs (mad/made).
Conduct whisper-phone echo reading during decodable passage.
Tier 2: Targeted Scaffolds
Color-code patterns: highlight digraphs in yellow, magic 'e' in green.
Provide tactile reference bookmarks with picture keywords (ship, thumb, kite).
Pre-teach decodable reader vocabulary before paired reading.
Tier 1+: Sleuth Extension
Compound word detective hunt (sunshine, backpack, campfire).
Have students write their own 2-sentence mystery clue containing at least 2 target patterns.
Detective Exit Ticket: Hand each student an index card. Write one mystery word on the board (e.g., chase). Students must: (1) underline the digraph, (2) put a dot under the long vowel, and (3) draw an arrow from magic 'e' to the vowel. Students hand in the card to earn their official Sound Sleuth Detective Badge!
